Pick one productivity suite and you live with it for years - it shapes how your team writes, meets, shares files and logs in every single day. Microsoft 365 and Google Workspace are the two serious contenders, and the honest answer to 'which is better' is 'better for whom'. This is a practical, UK-business comparison that ignores the fan wars and looks at the decisions you will actually feel.
Two philosophies, not two copies of the same thing
The biggest mistake is treating these as identical products with different logos. They grew from opposite starting points, and it shows.
Microsoft 365 began as desktop software - Word, Excel, Outlook - and added the cloud on top, so it shines when people want powerful, installed applications and deep formatting. Google Workspace was born in the browser, built around real-time collaboration, so it shines when several people edit the same thing at once with zero friction. Neither is wrong; they simply reward different habits.
The documents and email comparison
For day-to-day creating, the gap is narrower than partisans claim, but real differences remain.
- •Power and depth: Microsoft's Word and especially Excel are more capable for complex documents, advanced formulas and heavy formatting. Finance and data-heavy teams notice this.
- •Live collaboration: Google's editors handle many people in one file beautifully, with a simpler, lighter feel. Marketing and project teams often prefer it.
- •Email: Outlook (Microsoft) is the heavyweight for calendar-driven, rules-heavy professional use; Gmail (Google) is faster and cleaner but less feature-dense.
- •Compatibility: if your clients, accountants or suppliers all send Office files, staying in Microsoft avoids endless little conversion annoyances.
Meetings, chat and the daily glue
Both suites bundle video calls, chat and file storage, and both are good - but they pull in different directions.
Microsoft Teams is more than a meeting tool; it tries to be the hub where chat, calls, files and apps all live together, which is powerful but can feel heavy. Google Meet and Chat are lighter and simpler, doing the core job cleanly without the sprawl. If you want one dense, do-everything workspace, Microsoft leans that way; if you want fast and uncluttered, Google does. We compare the meeting tools specifically in Teams vs Slack vs Zoom.
Security, admin and total cost
On paper the headline prices are similar, tier for tier, so cost rarely decides it alone. The deeper differences are in security depth and administration.
Microsoft's top business tier (Business Premium) bundles unusually strong security and device management for the money - identity protection, device control and advanced email defence - which is a genuine advantage for a security-conscious SME, as our plans guide sets out. Google's admin console is famously simpler to run, which suits firms without dedicated IT. Whichever you choose, remember neither replaces a real backup - see our backup software guide - and identity is the new perimeter, which is why identity and access management matters on both.
So which should you choose?
Match the suite to your team's centre of gravity rather than to a feature checklist, and the decision usually makes itself.
Choose Microsoft 365 if you rely on powerful desktop apps and complex Excel, exchange Office files with clients, want the strongest bundled security, or run Windows-heavy with on-site systems. Choose Google Workspace if collaboration is your lifeblood, you value simplicity and a light touch, your team is browser-first, or you want the easiest possible administration. And if you are mid-migration either way, a tenant move is a project in itself - our tenant-to-tenant migration guide shows the scale of it.
