I'm going to make an addition to my previous post: I actually like pretty much every company for something. Though, overall, I think I've clicked the most with MVP/Axiom
MVP/Axiom for their customer support, consistency, and plastic
Legacy for the tight community, amazing molds, great plastic as well
Innova, Discmania, and Millenium for the history, some of my favorite baseline plastic on the market
The Trilogy for some of the most unique molds on the market, good feeling plastic, trying constantly to promote and grow the sport
I can keep going, but these are the ones that I mostly throw/ liked throwing the most. I'm not trying to be cheesy by pulling the "well every disc company is great!" kind of thing, but I honestly really really like throwing almost every brand of disc. It's hard for me to stick with one manufacturer (or disc, for that matter) because there are so many amazing discs out there to throw, each with their own merits. Just some food for thought. Cheers, and happy discing!
