I'm a recent BOA convert as well. Most BOA boots I've tried are on the stiffer side so I can't say I'd never go back to a softer boot, but once my 32 Focus BOAs were broken in, I was in love. They are the stiffest boots I've owned, by far, but they haven't affected my progression.
BOA isn't a scam, it has pros and cons just like any other speed lace system out there. For me, with two reels, I can dial them in perfectly and they stay dialed all day. The system is self contained so I don't have to deal with a rogue lace if they get untied. Its faster. The cons, boots are heavier and stiffer. Once the BOA lace breaks, its not a 2 minute fix (but neither are the solomon laces)
