As a great all-around synth with ton's of great samples, a great solid sound engine, good features and great Operating system, I would recommend the Korg Triton Extreme. I've had the yamaha Motif ES 88 and I sold it as it was just too big and bulky to gig with. The sounds of the Motif are really good, but the OS stinks.
I've had the Korg Triton Pro for years, then upgraded to the Triton Extreme about 2 years ago. It is my 'go to' synth for gigging. It has great Acoustic, natural samples, great 80's synth sounds with the additional MOSS Z1 board. There are literally tons of free patches in the public domain.
Give it a good look...
