I explicitly benched my miner against Claymore 9.7, and i also explicitly said i couldn't beat it, by an order of magnitude. It can push my HD7850 1G to 450, i cannot go above 370 
but yes, i'm still second, other miners are still worse. But i found jce a lot more stable than Claymore 11.3 and faster on cards with 2G+ memory.
On RX550 and RX560 jce should be the best if configured properly, which include waiting for 5-10 minutes after each start to let it warm up.
On RX460 2G use multi-hash 416, 432, 448 or 464, worksize 8, alpha 4 or 8, beta 64. On 4G, use same and multi_hash 464.
Otherwise try the 0.31e, the most stable so far, it takes ages to compile its opencl but may mine a bit faster than 0.32 in some cases.
