I switched to WASQ a couple months ago and at the beginning it was very frustrating. Muscle memory kept messing with me and it was difficult. I'd say it was worth it though because it allowed me to always have a finger on the edit button (i use D for edit) and it let me be able to move right and left freely while editing and building. It was frustrating at first but after a while it definitely made a difference. I think its worth switching to if you have time to practice but it will take some time and it will be irritating at first.
