Yes, the Shadow+ has a RD lockout that reduces chain slap (and falloff) which is a plus running a 1x .
Its also positioned more inward and less likely to scrape in case the bike falls over.

For those who want some idea of the bar I used, here are 2 (I actually bought both; but used the first one)

Lots of good info on the STI+9sp RD, I might still do this on my tribike
