It's not really "far superior" unless you have such high status that you always get upgraded--which is going to require something in the 100K+ miles/range. Airline Clubs and TSA Pre also help although those aren't directly related to frequent flyer status. There are some benefits to mid-tier status (e.g. Economy Plus on United) but you're still pretty much just flying coach and have all the same issues related to flight delays etc. as everyone else does.

100K+ miles isn't that much if you fly frequently though, a plenty of people do multiple times that.
