fantom g compared to the m3

ive been testing the fantom g at my local music store lately, and they had it hooked up to some roland keyboard amp/speakers, so ive been sequencing songs really quick on the fantom, but it has sounded really boring, and i think it was because of the amp they had it running through, today i went in and they had the fantom hooked up to some studio monitors. the song i sequenced on the fantom sounded really tight and clean, i was amazed, then made another beat on the m3, and was not so impressed anymore, even the gimmicky kARAMA sounds seemed to fade away from my mind. one thing i always noticed about the sounds on the fantom, was the way they seemed to blend together very harmonically and naturally when sequencing a full song. sometimes sounds would not stand out until the right sound had be complementing it in the mix, something i haven't felt with other keyboards. they also dropped the price in the past few days, the fantom g-8 is now down to 3100$, im hesitant to buy though after reading so many user gripes about bugs, however when i bought the fantom x7, i saw a similar amount of complaints about its operating system bugs, and quite honestly i never ran into any "bugs" on the fantom x7, everything worked fine that i needed to, the arps, the chord mem, the rhythm maker, pro edit, and the keys and knobs, however there were a few things i would have liked to see improved, such as a drag and drop window that makes it easier to make custom drum kits and then allowing key ranges inbetween the drum kit samples. if that makes sense, not a combi keyrange setup, just a single track set up, so say i want five keys for a snare so it has those 5 key pitches avalible.
