They're both good options, I also had this issue when choosing between Point Blank in London or Leeds Conservatoire, I ended up going for Leeds. I'd recommend listing some pros and cons for each, open days also help a bunch for making your final decision. There's one coming up for Leeds on the 1st of June, I recently went to one and my mind was made up there and then. It's got so many facilities and there's a really friendly atmosphere but I'm sure Trinity Laban is similar. I think being there gives you the most insight into how your uni life could look like and whether you can envision yourself spending the next 3 years there. Maybe check out their websites and read some of the currents students experience, look at the virtual tours of the buildings, look at the course content you'll be studying, also think about location and the accommodation you could be staying in and how far it is from the campus. If you end up choosing Leeds, I hope to see you around!
