M365 via the web only, versus an app

Over the last few weeks, the Outlook app on my Mac, seems to take longer than usual to send or receive emails. Various troubleshooting steps have already been taken.

My question for each of you is this, have you switched from using Office apps (on Windows or Mac), to purely using the web versions (OWA, Word, Excel, etcetera)?

If so, does it seem to work well, and thus worth it?
