They yield about the same, I once did a test on 2 rigs, at the same time ( both 24 hours ), same pool ( 2 times a 12 rig 1080 ti )
Hashrate on Bminer a lot higher in the console, on the pool the gave the same. ( slightly difference, not word to mention )
EWBF is no longer worked on ( since a long time )  Bminer is, but some people have their thoughts about that Miner ( connections it makes, maker says it's against a mitm attack )
Just go with what's stable on your rig
