Aside from carrier level NAT 5g internet thwomped Xfinity for quality in my neighborhood (this may have changed now that there's competition).
My choices (at the low end)were:
200/6 cable $75
75/50 5g $50
These were observed speed. The 5g was sold as 150/50 and cable 300/6. To get acceptable upload speeds to do remote work with cable was $185/month (I forget if that was 25 or 50).
Verizon ran fiber and now I'm paying $50 for 300/300 and getting pretty close.
Xfinity is now offering reasonable plans for $50 also, not sure if that's because of fiber or 5g. It could be either.
