Ostensibly, they are all the same as far quality and value for money. You are from Singapore, and will be paying full freight in the time of COVID-19, as it were, so I suspect that would have to be calculated into your offer from Univ. Of Bristol.
In full disclosure, I am a Bristol Grad, and I for the life of me can't understand or comprehend how anyone can qualify it as being any less prestigious than all save Oxbridge. Exeter, Durham, UCL, Manchester degrees will all get you where you want to go, save maybe some entry level position at a few US Firms who have all have a very small intake.
On balance, its your grades and application that will make or break your success. So take this whole prestige thing with a healthy grain of salt. Durham is no more prestigious, just as Exeter (et al) is no less prestigious, anybody who blathers on about it, is ill-informed.
Lastly, what have you seen to make you say Bristol is average compared to your 5 choices. And perhaps you should not consider attending it, if you feel so maligned.
