swae got more potential as a solo act than quavo - swae got better bars, he's got hooks, got the harmonizing/singing going, and has pretty much the same energy as jimmi. don't really matter tho, outside of top dudes like future, kendrick, cole, and sean, aint too many solo acts putting out songs with just them anyway, so like most dudes, it will be feature heavy.
i also think he did his thing on that mike will bars of soap track - spit bars, no hook, for like 4 minutes straight. wasn't mind blowing bars, but showed me his versatility
