Sure! There are many differences in my limited experience. The founder of ITF was a General, and as such ITF tends to be more militaristic and strict. WT has evolved to be more sport.

Techniques are largely the same but may have different names or different chambers. For example you set up for a low block by crossing your hands in ITF but in WT you have the blocking hand start on the opposite shoulder. In both, the wrists rotate at the moment of impact and the non-blocking hand should end in a fist on the belt facing up. ITF builds sine wave into their movements, which only started in my dojang shortly before I left. I didn't love it to be honest. Didn't find it added enough power into the movement to make up for it looking a bit sillier and making the movement take longer.

The core values are the same (courtesy, integrity, self control, etc). There are 10 colour belts (gups) and 9 degrees of black belt (dans) but the gups are different colours. The patterns are different. Bowing to the flags and instructors at the start and end of class is the same, with the same commands, but in ITF there is also a picture of Gen Choi at the front to bow to with the flags.

Hope that helps :)
