I think that old stuff is pretty cool; brings back a lot of memories.
My family used to use the old Coleman white gas stoves and lantern. I discovered recently that my dad still has them, and they're all still in good working order, but he doesn't use them often.
When the time came for me to get some of my own camping gear, I was fully immersed in propane, so that's what I have for lanterns and stoves. I've contemplated tossing them into the camper a couple times, but they just haven't made the journey yet. Those mantles, especially after they've been burned, are really fragile, and I could see myself having to replace them EVERY time I wanted to use my lantern. It might not happen that way, they tended to last a while under some pretty extreme conditions when I was younger...
Since I have a propane campfire, my long-term plan is to get a propane tree to put on the 20lb tank I carry for the campfire. Then I can mount my lantern on top, hook my little stove up to one of the other outlets and my campfire to the other and have a complete propane setup.
I still use a white gas fueled "Whisperlite" for backpacking though.
