I think these jeans have its place. I've seen some very well fitting 7s and other supposedly premium brands except they have some insanely big and inproper pocket stitchings, not too mention they are very expensive. I too recently bought a pair of jeans with elastane. Brand's some unknown shit called Big Star. Comfortable as hell with a nice dark wash. I have no problem executing a roundhouse kick in those. Better than those trackpants or kungfu bottoms and I won't have anyone sway my opinions otherwise. If you like yours, good for you.
Incidentally, I also made my first foray into Raw denims. I took Whodini's advice and got a good (read: expensive) pair, a 5EPs LDB in raw. Still waiting for it to arrive. Hopefully it doesn't disappoint. Crate denims seem good too but I only have budget for one pair.
