I like, Kevin have done both and still own both 96 Impala SS... plus some other B/D body cars.
The LS3 with a BTR Stage 3 camshaft, BTR dual valve springs and Scorpion 1.7 Roller Rockers is a lot of fun and I love to drive it on a nice cool sunny days. LS engine are easy to swap cams,water pumps, plugs, wires,ect and have a WOW factor when I open the hood at Friday night car stop, but after nearly 20 engine builds I still like a nicely built 396 or 383 LT1, with great heads and all the other good stuff we all know.
I have a nice 396 build with AFR heads that produces just about the exact same rwhp and torque as a brand new LS3.
Torqueheads stuff looks very nice, I just wonder 5 yrs from now if I need some replacement parts will they in business anymore.
The 396 and LS3 costs were nearly the same, but I did all the labor myself. No short cuts.
I really all depends on what you want to do and if you can do the labor yourself.
I do not drag race at the track and prob do noy have the fastest impala SS in the Midwest, but it is fast enough for me and I still have Air Conditioning but barley ever use it lol
