but it won't feel like a 500hp small block, big block, or gen 2 hemi. I think you're making an unfair comparison of Gen III vs LS. Most people looking to go LS aren't coming from a GenIII(Excluding the gray LX challenger from drag week.)
Are LS swaps boring and over done? Yep, but there is a good reason why they are done in so many cars. So it may never win a car show award, but it will a great performer that could be daily driven. Unfortunately I can't say my small block efi'd car is a good daily. :(
