I've carried a 632 in 32 H&R for a number of years, with Buffalo Bore 100g +P ammo that actually chronos with a bit more muzzle energy than Remington's 38 Special +P 158g LSWCHP round. (Both out of 2" J frames on the same day over the same chrono setup.) It's plenty of gun, and lots of fun to shoot with lighter practice rounds.
I thought I'd like a 327, but couldn't see paying the current prices for a S&W, so I got a Ruger LCR in 327. As 505Gibbs notes, the full power 100g loads (from Speer and, I think, Federal) are eye opening in a gun that size. They reminded me of the one (1) round of 357 Magnum I've shot out of a J frame. Never again for the 357/J frame combination for my old hands and joints. And although I shot several dozen of the full power 327 loads in the LCR, I've decided no more of that either. I much prefer the size and layout of a J frame, just haven't gotten around to selling the LCR yet.
The rest of the factory 327 Federal loads that I shot all chrono'd below the energy of the 32 H&R Buffalo Bore loads I already carry. So I can't see the value of a 327 J frame for me as a carry gun. I get all the power I need in 32 H&R ammo, and shorter cases which (I think) are slightly less likely to stick during ejection than the 327s.
BTW, the hot 327 Federal loads are REALLY LOUD! I'd be concerned about some hearing loss if I ever had to shoot one of those without a good set of ear protectors on.
