There was a ball fitting guide on this web site. I have used it before. They ask you questions about your game which you apparently know. Then it recommends what ball you should use.

1. NXT Tour. Performs more like the Pro-V1x.
2. About equal. Even Pro-V's won't stop if the green is super hard.
3. Personal choice - I prefer a softer feel so I prefer the Pro-V1 (moved from NXT's about 3 years ago) over the X.

NXT Tour spins less, Tour S will run out less on hard greens, chipping & pitching is probably a toss-up.

That is a tough question. Not sure if you've looked here (www.titleist.com/golf-ball-fitting) but it could answer some of your questions!

Tricky decision on your hands. To answer your first question, they have similar long game spin. In regard to your second question, the NXT Tour promotes a higher ball flight which in theory would stop quicker on firm greens with approaches. The main difference between the two is feel. NXT Tour is a firmer ball whereas the NXT Tour S is softer. All comes down to preference. When it comes to chipping, if you are struggling, I would strongly recommend trying out the Pro V1. The Pro V1 seems to match what you were asking about. I would highly recommend them!

I think it's a personal taste situation. I love a soft-covered spinning ball but then I don't put a lot of side spin on my ball as a rule. What works more than anything else for short game is to find a ball you like and stick with it. Knowing how your ball will react to your short game shots will save you tons of strokes, IMO.

I prefer the 'S' for all the situations you mention. I've been using them for about a year now, and it is my ball of choice at the moment. Another reason is that I can't justify the expense of the V1 and V1x
