I think that if we were to ignore Swords Dance and compare Garchomp to other Pokemon, you'd find that there are generally better alternatives.What's Mew got over Gengar? I'd say superior defenses but weaker resistances go along with the pure-psychic typing. I think that if you were to ignore Baton Pass and compare Mew to other Pokemon, you'd find that there are generally better alternatives.

It is kind of hard to selectively ignore a move which is the practically the trump card of the subject in question...
Mew can and will use Baton Pass and its damn good at it, if not the best there is. The second it passes off that +2 NP to something like Salamence with its STAB Draco Meteor. You are looking at virtually 2 instant dead Pokemon, almost guaranteed. 3 if you're lucky enough and all that is only one option.
I think another important thing here needs to be stressed very clearly. Strategies have to adapt and to do that you need options and availability. In the case of Mew, it can do hundred's of roles yet it only ever does one thing. Yet despite this, it does that one task so well its near uncounterable even if you know its coming.
Its the same principles behind things like Specsmence or practically all the Ubers in general. It doesn't matter if you know its coming, you still can't stop it happening. At best all can be managed is damage control, lessening the impact of the blow. BP Mew is like that in even if you try to counter it, you just can't reliably because its too well rounded.
There is something infinitely more broken and dangerous about something which can do anything it likes. Yet chooses to do only one thing because it is still superior.
