I know that a lot of reviews of the Q Suites have been stellar...I've never flown on the Q Suites planes so I can't comment on those. I will say that one of my favorite business class flights of all time was flying a JL 787-9 with the old sky suites (the Collins Apex Suite)...it's a long flight and I really valued the increased humidity and cabin pressure on the 787 and I flew in a window seat, which feels amazingly private with those seats even though there's limited seat storage. It was really a really comfortable, cozy seat, the service and food were very good, and I'd definitely recommend it. On the way back I flew the same seat in an aisle and it was a much different (worse) experience than the window.
