Sanyo Eneloops are still NiMH fundamentally. They're just optimised for low self discharge.
Personally I have only bought off-brand batteries for compacts, and they have performed as well as the original in that case. But that is usually more due to the original manufacturer battery costing a ridiculous proportion of the whole camera cost, up to half! With DSLRs the battery cost in comparison to the body is much less significant.
As for removing from the camera when not in use, I can only assume that is a safety precaution for the paranoid. I never take LiIon batteries out until they need charging, and for normal use I can't say I really notice any significant discharge when not in use.
I do echo the comment about the flash though. I have the Sigma ringflash, and that seems to suck batteries dry even when off. So I do take batteries out of flash units if I'm not using them for any long period.
