Any of them of course. Why wouldn't you swap to a better option?
Gmail + all the Google shit I get for $16/user/month + the hassle of switching would be very hard to get me to move away from for something that is anything but monumentally better. Even then I’d be super skeptical. Google is good enough and I probably wouldn’t switch.
Also for commercial stuff, there’s obviously a cost of switching. For personal stuff there is as well but it’s generally close to 0.
For me, for example, I wouldn’t switch from Apple Music to something that cost a penny less and was a better experience or whatever. Same with 1pass. I like the solution I have well enough and both are cheap enough that it’s not worth thinking about how to export/import or whatever and then learn the new system.
