If you want it to fit in a gig bag pocket or on top of 2 vertically stacked One 10s, then the + is ruled out. IME, having the sweepable mids is worth the price of admission and larger size of the 800+. I don't use the deep or bright switches, but selecting the low mid freq I wanna bump allows me to thicken to taste, and having control over which upper mid band I cut allows me to erase any "gank". I was happy with the 800, and am even happier with the +. Unless you play both, there's no way to know (and certainly no way for me to know) which you'd prefer
