Honestly, upgrading the Q is generally not worth it compared to the others. The amount of burst damage it provides to an isolated target is pretty crazy, however, every other evolution provides so much utility (i.e. ranged slow on W, refreshing jump + increased length on E and damage reduction + extra stealth + extra damage from passive on R) that it is very difficult to justify evolving Q over the others.

I'd say if you are already starting to snowball, then upgrading the Q is a good idea. Otherwise, it is best to evolve the other abilities instead.
