I think this is pretty solid, and with finals being so late this year some of these groups are going to be CLEAN. The only ones I have a different opinion on are 13-19 range, and Red Wave. I don't see Vigilantes in, personally, and I view Quest similarly. I think Connexus or Redline have a solid chance of making it in over each of them. Redline is especially on fire this year in what is quite a rebound for the program. Red Wave was also a big surprise for me this past weekend. I wasn't sure what to expect as they've never really been top of the pack in PIO, but the mid-season promotion was well-deserved. I don't know if it'll land them in finals but I think they'll be pretty close.
Matrix is the one huge wildcard for me. There's so much that could go wrong in their show, but when it clicks it really clicks. RCC is also in a similar boat, as we saw with the prop meltdown in their finals performance last weekend. I'm overall pretty impressed with this year's ~top 6. Some are sticking to their proven formulas, while others are taking a big risk and trying some really unique stuff. I'd be happy with any of them taking it, but think the top 3 are pretty locked in as you have listed. I guess if I had to pick a favorite for this season I'd say Rhythm X as their show is a bit of a hype, but Pulse was already top three clean weeks ago so who knows what will happen.
