Some people underestimate the capabilities of ISP provided gateways. Some of them are very high quality hardware with faster CPUs than many high-end routers and tuned for compatibility radios. Locked down firmware ensures higher level of security. ISPs don't want support calls. Not everyone is obsessed with changing settings anyway.
And it is very true.
I changed operators a few months ago, between tests I left my ISP router and, although it is true that I have not used it for more than 4 or 5 days in a row, I was pleasantly surprised.
The band steering operation is simply great.
Otherwise, it's normal, but there is something I want to do with said ISP router and I can't, for that reason, I'm looking for a neutral one.
I don't need a "beast", I am one of those who, once they have it configured and operational, I don't usually touch the configuration at all.
Stability, functionality, everything I can through cable (tele work) but if I buy a router and they tell me "the band steering works very well" and when I have it, it doesn't work at all... well no...
After already discarding the brand I used before, because apart from that "problem" I have seen other basic ones (no connection with IPv6 when my provider gives it to me, among other things...) I went to a forum of my country, to ask for recommendations, and here I ended up...
Regarding the other posts, I can't give an opinion, here in Europe, there is everything, the normal thing is that they come only a little, and people, if they want some halfway decent Wi-Fi, need to resort to higher priced offers, or put in AP's or repeaters or similar.
Although, as I mentioned, my ISP has pleasantly surprised me in all aspects...
Maybe in a few weeks (if I continue with the position) I will have to eat what I have written, hehehe.
