Unfortunately, folks use weight as a valuation of "better"..
I can not think of single keyboard line that the heavier keyboard was not the better keyboard..
Personal taste is what makes the right decision for us..but should not make it "way better" in other folks decisions..
I only compared side by side the Tyros3 and G70...the G70 was ...."way better"..
SMF play, and all editing was better on the G70...and honestly ..most of the sounds on the G70 were better...especially drums, organ, and piano..
Personal taste..I am sure..
