About 90% of the time when I see people arguing about DAWs that is basically where my mind goes, the same buzzwords that can relate to most DAWs. Everything else imo is preference, I have never demoed Reaper but not because I dont think it's as good as what I have now. I have been using my DAW for almost 11 years, I'm still learning it and still humbled by it. I dont understand the need for polarization either as I am just completely indifferent. I do think sometimes people have something to prove, more often to themselves me thinks. However I do agree that Repear users can appear to be fanatical but I can think of plenty of others that the same could be said about. Perhaps Reaper users have maintained that fanaticism longer than others but that could simply be because Repear gives them good reason to.
Anyhow, in my eyes it all still and always will boil down to "to each his/her own" and arguing about it is like trying to teach a pig to sing. It only wastes your time and annoys the pig
