I wrote a massive reply but the page crashes. Agreed with Sophie about life in Bath but pay attention to housing because the majority of student houses available ARE crap. Freezing cold, inefficient boiler and poor insulation are quite common. One of my previously landlords only finally changed the boiler a year after I left even though it was rated E on at least 2 aspects when I was there. Sheffield's fancy accommodation is so cheap in comparison to the things you can get in Bath. Bath however is super walkable, and is a beautiful city.
Uni wise, I have a complicated relationship with Bath because I was a terrible student who wasn't able to push myself to improve and perpetually falls asleep in lectures while sitting in first row. (I fear my notoriety will prevent me from ever applying to any architectural jobs in Bath and I change to an adjacent field anyway so nvm) However, I do think that Bath is not a university for students who need a lot of guidance and there are more stuffs that you end up having to teach yourself that makes you side-eye especially if it's international student's tuition fee pricing.
Bath's technical aspect is tough only in the first 2 years and often over-exaggerated because if it sounds reasonable enough, the ones who grade your studio projects won't care if it's a bit off. It's just a lot of architectural schools don't teach technical drawings at all that makes Bath look miles better. Even then, I once asked my tutor how I can specifically learn to draw details correctly and he just said, you'll learn once you go to work. In terms of program learning, I have a friend who worked in complete analogue and still does fine. She applied to a pretty posh firm and even they were shocked at the quality of her 2:1 portfolio. Bath really makes you feel smaller than you actually are honestly.
Workload in Bath is A Lot. Students from other uni coming in to do Masters at Bath for example struggled a lot while it's a regular Tuesday for Bath students. But it's not impossible to have work life balance. The best students in my year were doing just fine but it takes discipline, strong personality and strong belief in your design so that you don't get pushed around by tutors who don't remember what they said last week and end up changing your plan for the 7th time. (Do believe what Head of Year tells you to change though because they do most of the grading).
Creative aspect wise, it will never be as conceptual as other universities are but it seems that they are improving. As I said, the stronger your conviction is, the easier you can push the boundary of being creative and staying grounded. You can look at previous yearbooks and compare the style of the 2.
The tutors in Bath are a mixed bag but the real horror are visiting tutors who sometimes treat students like punching bags, the teaching fellows and regular going ones are fine though. My former employer is actually a tutor for 6th year and he is very nice and super helpful. A tutor can be great or not great depending on the students basically and you have a chance to choose your own tutor in the final year still. I didn't get mine so I was paired with someone who I have never studied under.
Overall, the most important thing that makes or breaks your experience is how much you believe in your own passion for architecture. If architecture is not your end all be all, Bath might not be worth the stress and money but that can be said for the whole profession.
