Gem is usually two years ahead on the competition.
None of the features are coming from other brands, their earlier wk series have everything yamaha/roland/solton came later with.
Still today there's no arranger which can beat the sequencer f.i.
The styles is a matter of taste.

As the genesys is completely renewed in all aspects I would not be surprised if this board beats any arranger on the market today.

It should be available end of may in europe and somewhere in june in usa..
