No real surprises there.
Ronnie is the best breakbuilder.
Selby has the best temperament.
I'd argue that there isn't much of a difference between Tactical Astuteness and Safety Play. But then, I'd also point out that both Higgins and Selby deserve mentions on that score anyway, so it was just a way of being able to mention them both.
Technique is a pretty silly one, really. Different players have different techniques. There isn't one right way to play.
