Your shitty last mile DOCSIS3 connection over 20+ year old coaxial copper is not a reflection of the quality of an ISP backbone... I realize that from a customer perspective the two are indistinguishable, but if you look at the quality of the router/switch equipment used by the top 50 ASNs (ordered by CAIDA ASRank) for major north american ISPs, it's vastly more expensive than what's used in countries where ISPs don't have the budget luxuries for $100,000 routers.
What benefit is it to me :)? In all seriousness we run things in US and Ukraine and while in theory you would expect there would be some tangible differences given the concerns you outline in reality they are not there. Major backbone providers also use cisco and juniper gear and are about as reliable as stateside providers. Residential providers due to intense competition offer way better service at a small fraction of the cost.
