OK so, I have terrible circulation- 35 years of diabetes plus all my family that aren’t diabetic, also have bad circulation- but even then, pogies plus my Fox Sidewinder Polars are good for all conditions I’ll ever ride a bike in. The Sidewinders are completely weird gloves, they’re made of a warm material but have no wind protectio- in fact, they’re vented- so they’re not actually warm gloves at all, without pogies they’re more or less an autumn glove despite the name. But with the pogie protection they work more or less like a really thick glove liner, with the pogies doing the actual gloving, and they’re mind.
Otherwise, like nobeer said, Perfect Curves. Amazingly warm, and completely truly waterproof, which is such a bonus- fall off in the mud? Don’t care. Have a snowball fight? Why not. Dirty hands after you fell off? Wash them in a stream. It’s all good.
On the other hand, teh insides quickly smell like something’s died in them, it’s comically horrible. And they’re kind of hard to wash, or rather, they’re hard to dry, because of being completely waterproof- moisture gets stuck in the fingers if you’re not careful. But I couldn’t be without mine now.
