UFC 44 poster is hillarious especially seeing how the fight went down.
If I had to pick best design it'd probably be 129. Hey the promotion did something right to get so many people there live. 144 would be a close second. 147 would be third and it's funny cause it did the worst PPV numbers ever. Just like the design. Also weirdly I liked the two cancelled ones from 151 and 176, not sure if they'd count.
Other favorite designs are Chuck v Randy II and III, Chuck with Rampage/Rampage v Hendo(basically same poster), 145, 150, 165, 179, 187, 188. 87 and 89 had GSP and Bisping holding up a hook think that's a good stance for a poster wish they'd done that more later on.
219 is best women's one IMO.
I find Bendo and Edgar to be the two least interesting MMA champions of all time yet love the poster design.
UFC 32 poster is sad af though.
