TamashiiHiiroka has some very interesting videos with quite some depth to them, definitely my favourite. Not an lper, though.
ChuggaConroy is the only pokemon lper I'm subscribed to that does pokemon, but it isn't his main thing.
I used to be subscribed to Marriland before the whole fiasco between Nintendo/Gamefreak and pokemon fansites a few years ago and he removed all his videos. Can't seem to get back into his videos now that hes lping again, though, for some reason. Just can't enjoy them.
