Pricey, but reliable

"The tube has a very good valve (does not unscrew) when removing a CO2 cartridge."
"It holds air and doesn’t leak… yet…"
"Tough durable and excellent quality"
"I've always had good luck with Michelin tubes, unlike Continental where I've had batches of bad tubes and valve stems that unscrew when I rewove my pump. I also like that the Michelin valve stems are not fully threaded so they don't wear out the pump chuck as fast if it uses a rubber seal."
"Perhaps not the cheapest tube, but the Michelin Airstops are my fav tube. First off, I love the threadless valve stems. Im not sure why more companies dont offer threadless stems. (Some Kenda tubes are threadless, too). Second, the valve quality is solid. I recently bought brand S tubes and the valves were sloppy, and I could tell when pumping up tubes. The valves didnt seem to close completely and I could tell as the floor pump was at the bottom of the stroke and the plunger did not bottom-out solidly. Third, the Michelin tubes dont seem to leak air as fast as other tubes. This is relatively minor, as I air up before each ride, but perhaps reflects the overall quality of the tube."
