Should I switch to T mobile from Google fi?

I just want unlimited premium 5G (unrestricted) as you only get 50gb on Google fi and I often go over. I pay $110 for 2 lines on Google Fi and they've offered me 2 lines at $127 on the Go 5G plus with T mobile. I'll be bringing two phones with me

Reading the posts here gives me second thoughts.

Love to hear back from anyone who did the same or has a better idea. Big thanks
