Long story short OP get whatever you want. there is a laundry list of pros and cons to the LS2/LS6, mods, what have you. It depends on how far you gonna go. If you shop for parts right there is not a big price difference between the two. I've modded LS1s, LS6, LS2s, and LSA motors.

So it seems I should be more concered about getting a low mileage well maintained car than ls2 vs ls6
And if I ever decide to mildly/heavily modify it appears that it wont matter much anyway
Well maintained is the most important part.
I did heads/cam/102 FAST/TB on my LS6 and it's pretty awesome, but whatever you do you'll just want more. You get to 450HP, you want 550HP. You get to 550, you want 650HP, and so on.
Whatever you get, just fix the wheelhop first. I did a GForce 9" and it rules. But at the very least get their axles.
Not to thread jack but how do you put in a 8.8 in a cadillac?
Seriously though: What was happening was that people were turning their differentials into little anti personnel fragmentation mines due to wheel hop. So as is the way with cars, people found a rear end that fit and it was a Ford 8.8 inch. The other advantage to the 8.8 is that you can get it in an independent rear setup already out of a 80s-90s t-bird, Lincoln mark IIV, and a few of the svt mustangs. So as has always been the way with things Ford's rear end is one of the better ones because its cheapish, and its fairly solid and its easily available in a junkyard. So creative steel made mounting gadgetry, spec'd a new driveshaft and new axles (since the lengths of all that changed) and GeForce did all that for the 9" rear end, cuz 9"ers are even better.
