I shall transit LHR T3 to T5 later this week and will report back. I plan to transfer landside. I think landside transfer might be faster (depending of course upon the queues at immigration, and if you just miss the train which runs every 15 minutes).
But... security is more TSA-like (shoes off in all cases, etc.) ...
I originated at LHR T5 a couple of weeks ago and shoes did not have to come off. Perhaps the origination drill differs from the connection drill.
