Who's more reliable/less prone to malfunction? - Olympus vs Panasonic

Of all the stories that I've heard, indeed Panasonic seems to have less reports of failures than Olympus, but in my case, both have failed or malfunctioned.

My E-M1 have been suffering the rear dial issue for quite a while, although I learned to live with it. I work it out for a couple minutes when I'm going to shoot, and it works for the duration of the shoot. So, not so bad for me.

Although, my Panasonic 45-200mm failed completely, to the point that it no longer focuses. It moves the elements, but never achieves focus. And I haven't dropped it. It has been in a dry box for quite a while, though, so maybe the oils have dried up. Although, other lenses have also been on the same dry box, and they are working flawlessly.

So, I would have selected Option 3: Both manufacturers are equally reliable/un-reliable

As noted by the Moderator, do not tolerate a failing rear dial on the E-M1. It will just get worse. I had mine replaced twice. After the second replacement, the dial action appeared far "crisper" and has has not "skipped" even once that I have noticed. Not sure if there was a minor re-manufacture of replacements or not, but it felt like a significant quality upgrade after the second swap.

(I also bounced the FT (not mFT) 7-14 zoom off concrete from something just short of 3 feet. The lens continued to work, but had a bit of a "hitch" when focusing. I had the lens reconditioned by the Olympus factory, and the lens has been just fine since, although the lens cap has a small ding in it to remind me to be more careful.)

As far as contrasting the two camera manufacturers quality, I can only say that I have been very satisfied with Olympus gear, but have not used Panasonic gear.
