Dabbled in it a little over the years, its good fun.
The boots are more comfortable, and you can get different stiffness bindings, in addition to older bindings vs NTN. A real stiff binding is easier to basically alpine ski on and takes more force to drop a knee. Soft bindings give you that awesome easy feeling but you can't be lazy and just alpine ski on em. Just preference, I'd say maybe learn on soft so you're forced to get the technique fast but idk that it matters that much.
I think the cool thing about tele is how ridiculously stable you are in a tele turn, so long and low. Do beware of diving your inside ski in deep powder during a turn though, that gets real weird.
The first, most important thing you learn is how to not fall on your face. if your weight gets too far forward, take a knee, it'll fix that. Flailing doesn't work nearly as well.
I'd say Tele is more fun when you are going slower and not pushing yourself, just enjoying it. More comfy boots are a plus, and tele gear is generally easier to convert to touring gear so actually I think it makes a really fun touring setup.
PS I think you're required to move to Vermont and grow a beard if you pick up Tele, its like a law or something.
