Yo dude, as you know I've got a Nismo 2 Way in the 32. The diff being locked constantly is absolutely brutal mang! I have nearly binned it (re: smashed side skirt) due to decel lockup!!
Basically if you go into a corner hard on the noise you've got to stay on it, lift your foot off the throttle and you'll likely be swapping ends.
I guess it comes down to your prefered driving style though. If drift and drag is your priority then by all means, but if to live the daily life I'd go the 1.5 as it's a bit more of a compromise between sport and safety.
