Microsoft product comparisons

Pick the right edition with confidence. Each comparison ships a feature table, a clear verdict, and an FAQ — written by ex-SAM consultants, not marketing copywriters.

How to choose, in 30 seconds

  • One-time vs subscription: perpetual Office (2021/2024) wins on total cost of ownership after ~18 months for a single-PC user. Microsoft 365 wins when you need OneDrive, multiple devices, or always-latest features.
  • Home vs Business: Microsoft 365 Family covers 6 people, 5 devices each, but cannot be used for commercial activity. Microsoft 365 Business Standard adds Teams, Exchange and SharePoint and is licensed for commercial use.
  • Windows Home vs Pro: Pro adds BitLocker, Remote Desktop host, Hyper-V, Group Policy and domain join. If you tick any one of those, you need Pro.
  • Server Standard vs Datacenter: count your VMs per host. Under ~10, Standard is cheaper; above ~12, Datacenter is.

Frequently asked

Office 2024 or Microsoft 365 — which should I buy?
If you use Office on one or two PCs and don't need cloud storage, Office 2024 is the better deal — pay once, use forever. If you need 1 TB of OneDrive per user, monthly feature updates, or coverage for 5+ devices, Microsoft 365 wins.
Windows 10 or Windows 11?
Windows 11 if your hardware supports it (TPM 2.0, supported CPU). Mainstream support for Windows 10 ends 14 October 2025, so for any new purchase Windows 11 is the right answer.
Server Standard or Datacenter?
Standard if you run 1–2 virtual instances per host. Datacenter is only worth it from roughly 12 VMs per host upwards (the math: Datacenter costs ~7× Standard but allows unlimited Windows Server VMs).
Office 2021 or Office 2024?
Office 2024 if you want the newest features and the longest support window (mainstream until 2029). Office 2021 if you want the lowest possible perpetual price and don't need the new Outlook, accessibility ribbon or modernised Excel features.

How to read a licensing comparison without getting sold to

Most comparison pages online are affiliate funnels: they declare a winner in the first paragraph and then justify it. A licensing decision does not work that way. Office 2024 and Microsoft 365 are both correct answers depending on how many devices you own and whether you value cloud storage; Windows Server Standard beats Datacenter until roughly the twelfth virtual machine on a host, then loses badly.

Every comparison here is structured the same way: a feature table with no omissions, the total cost over a realistic ownership period, the specific scenario where each side wins, and an explicit statement of when the cheaper option is genuinely the wrong one. Where the difference is marginal we say so rather than manufacturing a verdict.

The four decisions most buyers face

These are the comparisons people actually search for. The short verdict is here; each comparison page works through the numbers behind it.

DecisionChoose the first ifChoose the second if
Office 2024 vs Microsoft 365You use 1–2 PCs, want to pay once and keep the software indefinitelyYou need 1 TB OneDrive per person, 5+ devices, or continuous feature updates
Windows 10 vs Windows 11Your hardware fails the TPM 2.0 / CPU requirement and cannot be replaced yetYou are buying anything new — Windows 10 mainstream support ended October 2025
Office 2021 vs Office 2024Lowest perpetual price matters more than featuresYou want the new Outlook, updated Excel functions and support until 2029
Server Standard vs DatacenterYou run 1–2 Windows VMs per hostYou run roughly 12+ VMs per host, or need Storage Spaces Direct and software-defined networking
Perpetual vs subscription generallyThe software must keep running with no ongoing spendYou need the newest version continuously and per-user mobility across devices

Before you commit to either side

  • Count devices per person, not devices in total — that single number decides most Office comparisons.
  • Project cost over four years, the realistic life of a perpetual Office licence, rather than comparing month one.
  • Check the support end date of the perpetual version you are considering; a cheap 2019 licence with two years left is not cheap.
  • For servers, count physical cores per host and add CALs before comparing anything.
  • Verify the feature you are paying extra for is actually one you use — cloud storage is the single most over-bought line item.
  • Confirm the licence channel is transferable if you expect to change hardware within the ownership window.

Comparison FAQ

Office 2024 or Microsoft 365 — which should I buy?
If you use Office on one or two PCs and do not need cloud storage, Office 2024 is the better deal: pay once, use indefinitely. If you need 1 TB of OneDrive per user, monthly feature updates, or coverage for five or more devices, Microsoft 365 wins on both price and capability.
Windows 10 or Windows 11?
Windows 11 if your hardware supports it, meaning TPM 2.0 and a supported CPU. Mainstream support for Windows 10 ended on 14 October 2025, so for any new purchase Windows 11 is the correct answer.
Server Standard or Datacenter?
Standard if you run one or two virtual instances per host. Datacenter only pays off from roughly twelve VMs per host upwards: it costs around seven times Standard but allows unlimited Windows Server virtual machines on the licensed cores.
Office 2021 or Office 2024?
Office 2024 for the newest features and the longest support window, mainstream until 2029. Office 2021 if you want the lowest perpetual price and do not need the new Outlook, the accessibility ribbon or the modernised Excel functions.
Is a subscription always more expensive over time?
No. For a single user on one device a perpetual licence is cheaper after roughly two to three years. For a household or a team where one subscription covers several people and devices, the subscription is usually cheaper from day one.
Do you get paid to recommend one side?
No. There are no affiliate links or sponsored placements in any comparison. We sell licences for products on both sides of most of these comparisons, so the incentive is to get the recommendation right rather than to steer you.
