What plasma do you currently have...??
Right just my opinion... the oled I have is currently the best picture I've seen playing 4k hdr blurays especially jurrassic world fallen kingdom ... lots of detail pop bottomless blacks and still looking natural too like a plasma being brighter too..
For pure movie watching with ifc off in a pro mode 1 or 2 with a bit of tweaking.. it can't be beat.. but in full hd 1O8Op it beats but doesn't wipe the floor with my voltage tweaked kuro..
Considering its 11yrs old now too...For tv watching in general the kuro is near impossible to beat, sports etc and movies are still great... or gaming all rounder..
Purely movies oled all the way I think its better...not interested in gaming new stuff.. too long.. and not sure how image retention would be ...?? only old stuff but have a mame arcade machine for that..
The vt65 is great but for a grand and being 5yrs old I'd keep money and save towards the oled.. could pay that amount for the plasma maybe have a fault and then in a few months the 8O2 comes down further in price and would regret it.. get 5/6 yr warranty on new set too...
