All tubes are definitely not the same. The Conti tubes I've had have removable valve cores which can be unscrewed by certain types of pump. There is nothing more frustrating than getting a puncture at the side of the road then having your pump release all the air (and the valve core) once you've spent ages pumping it up to the required pressure, leaving you back at square one.

Vittoria Ultralites are good.
