well, depends what time j rpg you mean
if you mean the old time, the time of skies of arcadia, chrono trigger, seiken densetsu and ff 6-10, lost odyssey and and and, yes jrpgs are a thousand time better than western rpg
in 2015 you must consider that jrpg is nearly dead (i really wish it were otherwise, but it isnt), except dragon quest, star ocean tales, or surprise hits like bravely default there arent many great games anymore (we wait perhaps still years till dragon quest comes to west anyway):
ff died a horrible death with ff13, was resurrected with ff 13-2, 13-3, only to butchered even more cruelly with these shit games square enix called "final fantasy"
if i today play witcher 3 in 4k 60fps on the pc, i must say western rpgs nowadays are better than jrpg
but i must also mention that i prefer to play ff9 in 360p on the playstation 1 to all the best western rpgs, the old jrpgs will never be forgotten, these were the best games ever made!
