Korg Triton v/s Roland XP-60 v/s Yamaha Motif

Hi All

I have been using Yamaha PSR410 for years now (10+) and its time to
upgrade to a professional synth. I have used friend's Roland XP60 and
I like it. However, I wanted to hear other's opinions on comparable
Korgs (Triton, etc.) and Yamaha (Motif, S80, etc.).

I want to be able to play it live (portability is important) and use
it for indoor studio recording (sequencer, sampler, etc.). I heavily
use strings, violin, brass, flute and some indian instruments such as
Santoor and Sitar. I intend to do my own compositions specially light
pop, jazz, indian & arabic blends. And I want to use the keyboard for
next 10+ years.

Any suggestions/comments will be welcome.

Thanks

Vipul
