I always heard the Bosch stuff that was about $50/tube was the gold standard, but as best as I can tell it's been discontinued.
I use this

As said, this may be the only tube you ever buy as you really only need a tiny amount of it.
This is definitely an application where you don't want to just toss any grease on there, or for that matter use too much of the right grease, as if it flies off and lands who knows where, you can cause electrical issues and potentially gum up the advance mechanism.
BTW, I use what I like to think is an ideal trade-off. I still have points and a condensor in my distributor, but they trigger a Winterburn capacitive discharge unit. I get a stronger, hotter, and more reliable spark, but the points really only do have a small amount of current and ~12V going through them, not the ferocious high current 300V+ arcing from standard ignition, so the rubbing block wears faster than the contacts on the points. If the system gives me issues or I just want to rule something out, a switch(built into the CDI box) lets me set it to Kettering-type ignition. I can also switch the ignition off completely from under the hood, which is handy both when I'm working on the car and also, even though I don't use it this way, could be an anti-theft device.
