It depends on what I'm doing. Leading from one pasture to another, nylon or leather. Working with a horse that knows what it's doing, the same. Working with a green horse or going out on a hack that it'll get tied at some point, the rope halter. The nylon or leather halters we use have the throat release besides the pole buckle. Usually we leave the throat strap undone so all we have to do is slip it over their nose and pole and the halter is on. If they start to be a pain, then we do up the throat strap.

Kind of the same as usandpets, but a little diffirent ;)
I use a nylon for things like leading, tying, trailering ... pretty much everything. I use my rope halter for lunging(It's a CA rope halter, super long lead), bathing (I switch the lead :p), and under their bridles when we hit the trail, wether we will tie or not at some point. You never know if they'll throw ya, and you want best possible outcome of them being caught.
I like the rope halters because they don't have any metal hardware that could potentially break if I had a horse pull back while tied. Have yet to have one break where as the others I have seen break many times.
I love using rope halters for ground work and training and if you're teaching a beginner and you're switching on and off the lunge, you can put a rope halter of the bridle and snap the lunge on and off. I also think they have more feel when doing ground work. Bad side, they are awful to put on quickly, you'd have to buy a piece of leather for a breakaway halter, and there isn't a real place to put crossties on.
Leather or nylon halters can be breakaway, easy to put on, have padding, etc but I don't think they give a clear signal when doing groundwork. And they are at least $20 and if my horse is only going to wear a halter for an hour a week, why bother?
I prefer to use leather halters on my horses. They look really nice on the horses and I think they may be more comfortable for them to wear as long as they are kept properly cleaned and conditioned on a regular basis. I also like to know that if some sort of an accident were to occur, the halter should break thus helping to prevent serious injury.
I use rope halters for everything but floating, or if I need to leave a halter on overnight or in a paddock for some reason. I love rope halters and only use webbing ones if safety is an issue for some reason.
