I have however flown both(other people's), and really like the performance of both, I think the 4* does better at slow speed, and the tiger 2 seemed to be "smoother", but that might just be me.

That's pretty much what you would expect, since the Tiger uses a fully symmetrical airfoil and the 4* uses a semi-symmetrical. The 4* will be a little more stable (right side up) and the Tiger will be a bit smoother at aerobatics.
They are both excellent fliers in there own way.
