Is 5G on Google Fi Any Good?

I tried Fi last year, but the 5G was unbearable. So, I switched back to Mint Mobile (which has been great, in my experience). I'm considering trying Fi again, mainly because I want to use a line with an LTE watch. Fi has a good program for this. However, I can't do it at the expense of a poor signal (for both my watch and my phone).

For reference, I was using a Pixel 6a wth Fi before. If I go back, it will be on either a P9P or P10P

Appreciate any feedback.
