Easter baking, and complaints about silicone

Easter's around the corner, so yesterday I did my first baking run, making babas.

The thing is, I bought a set of silicone baking pans a while ago, and I'd only tried out the muffin ones before. The bundt/baba pan looked perfect - it's just the kind of fiddly, easily adherent cake you want to be able to peel out of a form.

Only it stuck like hell, with half of it breaking apart. And the half of it that didn't, was nowhere near as crisp as it should have been.

Thankfully I was making two anyway, and I had my trusty metal pan. But a question for the baking subset of the f-list - is this just how silicone pans are, or just cheap ones? Or is silicone only suitable for muffins?
