It is not one or the other. I figure 99.9% of the people that have a front projector setup, also have a flat panel.So I just happened across this grenade thread, lol. Agree with the consensus of course, but there is one thing I don't think I saw mentioned which to me is a huge factor.
Not all content warrants the same screen size. I don't have the fortune of having a dedicated theater room so I have to made do with a LR theater. I love having a big projection screen in my LR, but I don't want to watch some stuff on it so I have a retractable screen that drops down over the 65" OLED. Best of both worlds. My wife can watch game shows and silly reality TV stuff which does NOT need a big projection screen, but then we can fire up the projector for a movie or maybe some of the cinematic level Netflix 4K DV content. I like having *both* and it's just a trollish provocation to suggest that I must choose only one for all content.
Also, Jinjer f'n rules.
