Grape Dutch cigarillo's for myself, Vanilla Game's for a group. Like you said, blunts burn slower. They're easier to sit back, relax and savor the moment. I always feel like with joints every second that I'm not taking a hit is a massive amount of wasted session.
Plus, I like the way blunts taste. Vanilla Game's remind me of pancakes and syrup, and the Grape Dutches just taste so damn good...
I think joints are by far easier to roll, though. There's no outer leaf to worry about ripping when you peel it, no guts you need to dump, and papers don't stick until you intend for it to happen. With blunts, you pretty much have to apply some moisture to properly roll and if you use just a little too much or not enough spit it's pretty easy to rip/tear/split a blunt apart mid-roll. Basically, blunts require a bit more finesse, in my opinion, whereas joints are pretty much a 60-second process once the bud's all broken down.
