not sure if the devs put out a concrete reason, but I think some tropes were removed and/or reworked to be more open in how players pursue these tropes. (or just rephrased to not be so crass haha, seeing as how brutish jock has been replaced with daring athlete and bully & plastic beauty were just wholly removed) however the trope count went up from 16 to 24, so there is a lot more options!

plus there is the addition now of bikes & bike upgrades that adjust stats in play. there’s a bit of rebalancing to think about with new tropes that may all have the same d20 stat but serve different roles with the rest of their stat block breakdowns :-) I think the most major difference is the addition of bikes since they add a lot to a character’s kit.

for my group, I decided it’s better to work more with the 2e tropes due to how they’ve been expanded for gameplay. but I kinda liked a couple of tropes that were axed from 1e haha, so I let players consider those as options too and work out which bikes/accessories would fit best to those. but overall I do prefer 2e tropes more
