Guildhall vs Trinity Laban vs Royal Northern College of Music for a vocalist

Hi all! I’ve been applying to different music courses and i’ve had some offers! I’ve been offered a place at Trinity Laban on the BAMPI course (Music performance and industry) as part of the popular music department. I’ve also got a similar offer from RNCM on their popular music course. Then finally i’ve also just had an offer from Guildhall on their Bmus course with hons in Jazz Vocal! I’m now looking for every opinion I can get on these different institutions as I haven’t had a chance to visit any yet, and what offers people think would be best and provide the most opportunities out of these options. Thanks!
