are TH worse chokers than PRX?

PRX can at least win pacific grand finals

nope if th chokes 3 grand finals more then we can say that because th is still a young team experience wise of course

yes. PRX have won regionally many times and their 2 grand final losses were spread out-TH has lost all off theirs in back 2 back 2 back etc finals

I thought that was a known fact
Yes they're much younger but to choke this many finals in not even 2 years is a feat that no one other than Heretics themselves can beat
