The answer seems obvious (detachable) but I've read in an FAQ that they have weird RF cables that are hard to find converters for.
This is true... however, the RF cable can easily be replaced with a standard one. All you need to do is open the system up, and plug a different cable in (There's actually an RF jack
inside the system, you don't have to solder or anything). Of course, if you get the proper RF switch with the system, then there's no need to change anything at all.
You should also keep in mind that Odyssey^2 joysticks (the detachable ones) are not compatible with Atari joysticks... so if you go for the detachable model, make sure you get joysticks with it, because modifying the joystick ports is a much bigger job than switching the RF cable.
I'd say go for the detachable O2... but
only if it comes with joysticks, or you have a source for joysticks. Otherwise, get the built-in one. If you have problems with an unresponsive player 1 joystick (which shouldn't be too big a problem, since the O2 sticks are quite good), you can easily open the system and swap it with the player 2 joystick without soldering.
