Graeme's style isn't really to my taste either, but (without having been the victim of his bankside shenanigans) he explains tackle and techniques extremely well and, at the end of the day, I think most of his videos are perhaps aimed more towards beginners and novices. I also appreciate the humour he puts into it - all too often these "amateur" YTers are complete personality vacuums.
I'm a huge fan of Mark Erdwin - most of his videos are quite short and tend to focus on the fish and the fishing more than bait and techniques, but he puts some absolute lumps on the bank. He has a very quiet and calm presenting style, which may be more S-Kippy's taste, but I know some people find him and his vids a tad too sedate.
Carl and Alex are good for the sheer variety of fishing they do, and the regularity in which they post, but the editing and music does my chuffing nut in, so I only dip in every now and again.
Also, apologies for moving away from specific presenters, but the recent run of vids from Sticky Baits have been absolutely tremendous, not least an hour long carp vid with Yates and Bowler.
