I do like the look of the stock mirrors but as I mentioned hated having to swap in mirrors for doors off. Plus having the mirrors on the doors makes them a little more difficult to store when they are off.. less "stackable".
I switched to the A-Pillar mounted mirrors was back on my second JK. It was a progression. First set sucked. Vibrated all over. Stuck out way too far and generally ugly. I made some brackets to mount to the a-pillar and it helped with the vibration.
Later I switched to a rectangular convex wide angle truckers auxiliary mirror. At first the wide angle makes your head spin but soon I found it was far better than the stock mirrors and when combined with the adjustable arms solved any issues with visibility regardless of being doors off, full doors or softies on the half doors. I can see a really wide field of view behind me and parking lines are easy too.
Then I switched to a round mirror with a slightly wider field of view primarily because the rectangular mirrors were not period correct. The wider field of view allowed me to shorten the arms without having any issues with a-pillar visibility even with the plastic wind deflectors installed to keep water off me when the windows are cracked. The combination of the wide angle, short arms and an off-set mounting stud on the mirror work great together for positioning.
If there is any downside it is that the wide angle makes it a bit challenging to judge distance behind me but it's something I've gotten used to.
