I prefer the tape because I can get it. I don't know much about the paste because I can't.
Lately I substitute polythene for the general antiseize duty (for example, on wheel studs), but I still use PTFE on brakes, especially around the bleeder threads.
My caliper slider pins are silicon-greased and wrapped in PTFE tape, but I'm unsure if this is a great idea because of the slight risk that overheating could break it down and form fluoric acid, which isn't nice.
I never use type on a brake system. They're all sealed by the flare. Never saw tape used on slider pins... nor would I
On the nipples I mostly use it for anti-seize effect, though it may also reduce air suck when bleeding, when, pretty much by definition it is not sealed by any flare.
I've never seen tape used on slider pins (before I did it) either, but then I don't watch that many Youtube videos so I'm not claiming a "first".
Doesn't bother me. I'm unsure of the flourine release thing, but someone recently posted a pic of Volvo brake grease with PTFE in it recently., so its good enough for the Chinese....
