I'm starting the MArch at The Bartlett this September but I have come to conclusions from my research, my own experience and from speaking to current and former students. Essentially, with architecture, if you wish to do well i.e. aiming for a first etc. (which you should be) then it's going to be tough, I think third year at undergraduate I worked or at least tried to work (and ended up procrastinating) every single day except Christmas Day, and that wasn't even at the Bartlett. With regards to the Bartlett itself, from what I can tell it's only marginally more intense in terms of workload than any other school, the main thing which makes it more demanding is the quality of the other students and the general sense of expectation. I would also say to you, not to worry about the course lacking in "practical skills", nothing will really compare to working in practice for real anyway, and I know from working in the industry myself that students from the Bartlett are very highly regarded (the highest regarded in the UK for sure) at best, and seen as at least as good as students from anywhere else at worst. You only have to look at the AJ100 to see this. They ask the top 100 architecture firms where their favourite students graduate from, and from memory 27% said UCL, with the second most popular being Sheffield with 7%, then Bath with 6%. That speaks for itself really. Having said all this, wherever you go, its up to you to prove yourself, I went to an average uni for undergraduate, but got a first and the highest mark in the year and have landed a job at a top London firm. So go where you'll be happiest I guess, but don't be afraid to challenge yourself and go to UCL.
