Not an easy answer, there are lots of things to consider. They will both be the same resolution, I'd imagine - 1920x1080, so that makes it easier. It will come down to things like bezel size and input lag. Generally, the bigger the better with this stuff, but for me, input lag on tv's can be very high and bezels can be rather big, too. Personally, I also can't stand tn film panels either, but you might not be so fussy.
I think if i was to do it again and the 3 screens were only for a race rig, i'd want to go for tvs and probably bigger than 32". But as said, I'd be heavily researching input lag, what panel is used (i'd want IPS), and how small the bezels are.
