I also don’t read other reviews first - honestly ideally I would, but reading reviews takes time, and revising my thoughts takes more time, and for good or ill I’ve adapted my process to allow me to review all the games in large Comps during the time limit, so this is one of the ways I trade off quality for speed.
The plus side, such as it is, is that I occasionally entirely miss what’s going on in a game because I had an idiosyncratic experience with it, and write a blissfully ignorant review that provides a fresh, unique (and er, probably misleading) perspective - like with the Curse this year.
