Anybody have any new experiences or observations to share?

Mr aBroad is receiving a 6+ for xmas, and we're trying to decide on a cover. We've both always been happiest with the bumper-style cases (he has a Spigen on his 5 and I have a Luvitt on my 5S). He's zero-abuse device user (no drops, etc.), but still needs to be able to set it down, carry it in his pockets, etc., without worrying about scratches. Least bulky and unobtrusive is best.
