I keep BPs mostly, but also have a few corns. I find they are a really nice complement.

When my BPs are being anti socialable I know the corns will be up my arm and out of the enclosure ASAP (probably just looking for any rats I may have hidden on my person, but that is OK).

But I also like the heavier bodied snakes as well... bloods are a really nice forerunner for next species - or a Nic Boa. As well as SD Retics (not heavier bodied, but a really different vibe than a BP).
