Like most things, there are pros and cons with each, so it really boils down to preference. I've owned both and prefer left tilt, but I wouldn't pass a great deal on a great TS over it.
pros: blade tilts away the fence during standard ripping operations (with the fence to the right of the blade), arbor nut goes on from the right side of the blade and has normal thread orientation (which I find pretty darn handy for a right handed person).
cons: blade thickness changes skew the zero reference on the measuring tape.
pros: blade thickness changes don't impact the zero reference point.
cons: blade tilts toward the fence during standard ripping operations (with the fence to the right of the blade), arbor nut goes on from the left side and has reverse thread orientation (harder for a right handed person).
There are work arounds for some of the cons of both....folks with right tilt saws can slide the fence to the left side the blade so it tilts away from the fence, though it creates a non-standard reversal from normal ripping operations. For left tilt saws, it's fairly easy to adjust the cursor to compensate for blade thickness differences, or you can setup the saw using your thicker blades, then add a shim to compensate for thinner blades....that trick won't help with a dado stack, so you'll need to measure by hand.
