The U11 is a great choice if your intended recipient has some technical abilities. For a noob to flashlight User Interface, not so much. Basically, if you click it too fast (not easy on accident, but can happen) and the U11 goes into the strobe mode, you are now in a different UI set. If pro mode is on, the menu is much bigger too.
The X2R is one of those “too good to be true” lights that hits everything right for an easy to use light. Three modes, no blinky menu and a good charger built in. The cover is better than the U11 one in my opinion, I have both.
Good luck and congrats on Uni!
EDIT: Forgot to mention, the convoy clip fits the X2R perfectly as well, so the light can be pocket carried like the U11 as well.
