We started with UA but have mostly weaned ourselves off it after a few months.Voted 1e+UA as that's closest to the homebrew 1e-adjacent system we use.
We found specialization breaking our game and the extra classes/spells not really adding much value to us. Im sure once we get really familiar with the core books we might change our tune.
I did keep the +2 level cap for single classed demihumans though.
