Worth visiting both parks?

To the people that have visited both Universals,

I'm a college student and I recently went to USH with my parents in December. Now for Spring break, my friends were planning a trip to Orlando and they already booked tickets for Orlando's Universal Studios. I thought it would be completely different but I read that there's a lot that's similar between both. I have a small chance I can give it to a friend and not go at all, but I'd miss out on a chance with experiencing the place with friends.

Assuming budget IS of concern, I have been to USH less than 2 months ago, and I have the opportunity to save that money (as a student it's a lot), should I not go? Can anyone give like a percentage of how similar they are?
