Bcash doesn't have a solid community or a dev team behind it
Bitcoin Cash does seem to have a solid community and dev team behind it. As far as I know, it's supported by both Bitcoin Classic, Bitcoin XT, Bitcoin Unlimited and Bitcore. Bitcoin Cash will have a prominent place on the upcoming Shape the Future conference in Beijing.
Maybe I haven't heard of the community and the dev team behind Bcash but we'll see how it shapes up. Only thing I know is that Bcash recently had the 8MB upgrade to the block size but the general consensus seems to be down around the coin. Only time will tell.
The "general consensus" depends on where you look :-)
