What I dislike about the current system of feats vs ASI is that for any Dex based character the ASI always seems way better. It amounts to +1AC, +1to hit, +1 damage, +1 initiative, +1 to dex saves, +1 to stealth/acro. Feats don't really compete with that. For a Str based guy, they don't get the AC or Init, so feats are far more tempting for them.
My group feels that they are being sub-optimal to get feats before 20dex, so they would not get any before the end of the campaign. For Str types, they feel feats are a bit better, but vastly more interesting. For casters, they just got for stats, since caster feats tend to suck or not exist. Adding in some more interesting caster or out of combat feats could help.
I definitely feel that struggle, but...my elf rogue felt Skulker was worth more.
