Clen and test prop would kick in faster and of course the test would work to bind to AR in fat and thus help to burn it easier than Epi would, but then it's highly dose dependant, too; ie more is better. It's also highly likely that you would see some modest strength and size gains even in a slight caloric defecit. Epistane however would be a lot cheaper and still has some very real leaning and hardening effects.
You could get more specific recommendations if you give us a brief synopsis of cycle experience and if you've ever tried clen before, your hypothetical length of cycle, and your dosing for the two cycles.
