There are a few brands. In general, I like them a lot, but to perfume drawers rather than to burn. I've never really burnt them, so I cannot compare.
The standard ones are based on benzoin, which is a sweetish amber. I like the Santa maria novella, though they are expensive. In France, one can find very inexpensive ones in drugstores (simply called papier d'armenie), which cost a couple of euros per booklet. They're lighter but still good.
Francis Kurkdjian has made a couple in his collection, not based on the standard recipe but with some of his own perfumes. If I remember correctly, one is based on Lumiere noire - I own this - and one on Aqua universalis (though I could be wrong on the second). As with all Kurkdjian brand stuff, they are expensive too.
