I don't think the Triton/Trinity is better than any 2 other keyboards. When it comes to synth-engine, the Triton at least is simpler than the XP's. Of course the Triton is also a sampler, and can be expanded with an analog-modelling synth board. But I still think I would buy 2 other keyboards/modules instead of buying a Triton. The Triton seems (in my opinion) to be very expensive for what's on offer, and is probably not the best buy in the market.
