GPST training in London - how good is the training?

Hey guys, just ranking the GPST preferences in London as got to stay close because of family ties. Got no car so can’t drive long distance.

Which GPST programmes are the best in terms of local teaching, portfolio development, research, and training opportunities?

Any long distance driving involved? I’m looking to get a special interest in derm so would be great if there’s one among the rotations.
