I find it a relief to hear this. I couldn't help but think you'd get stressed at mobile services having very fluctuating performance.
I get excellent Three 5G here but when I tried it exclusively for a few months I had problems with websites loading, even though the raw download speed was fine. When mobile services get bottlenecked, it takes months to resolve and is more likely to happen as more people move over to 5G.
Heck, they resolved the problem here by putting up a new tower, not something you can expect to always happen.
