after re-watching the 5th season im still not 100% sure why Tony compared Feech to Richie Aprile but i have a guess. when Tony noticed all his cronies laghing like idiots at all his not so funny jokes, he knew they did so out of fear. but when he remembers the card game he see's Feeches expression and Feech isnt laghing. so did he basically relize that Feech wasnt afraid of him and would probably make an attempt on his life?
