Is Panasonic gear's reliability and durability levels comparable to Canon/Nikon gear?

Thought I'd report back on this subject, now that I've used 9 Nikons and 4 Lumixes on Aussie desert shoots over summer. Forty degree heat (Celsius), dust, vibration over rough roads and daily use for five months. All cameras worked hard doing time-lapses or handheld work. The flies didn't seem to bother the cameras except getting in the photos, but they sure drove the photographer mad at times.

Nikon

One Nikon died (a D7100 with about 75 000 exposures on the clock), one developed an intermittent minor fault (11 year-old D200 with 63 000 exposures, draining the battery prematurely), and the little V1 shut down in the heat, which isn't a developed fault - it's a factory-installed fault! The other 6 Nikons were trouble free even though most are old (only two Nikons, a 610 and a V2, are newish current models, others are a D300, D300s, D3200 and D7000). None of the many Nikon lenses gave trouble.

Lumix

All Lumix bodies developed faults, two lenses broke off bodies (one was just a plastic mounted kit lens, the other was the heavy ‘metal mount’ lens mentioned above), and a little 12-32 seized up in the dust. Three Lumixes were current models - a GX 85 (about 18 months old, viewfinder display went pear-shaped), a G85 (7 months old, still images sometimes corrupted, rear screen only working if opened and closed a few times) and an FZ1000 which developed stabiliser problems, and then the plastic base broke. The other Lumix was an old GF2 which started rapidly draining its battery.

All three modern Lumixes got rubbish on the sensor that showed up in images. The FZ was cleaned by Panasonic; the GX85 is out of action until it can also be dismantled. Seems the rubbish is between the sensor and cover glass. In 11 years of using digital Nikons and Canons in the bush, I've never encountered that problem.

The main problem with the Lumixes was operational. In AFs with video, all 4k cameras would focus and then ever-so-slightly defocus before the recording started. AFc wasn’t consistent enough for video. So with both the G85 and GX85 I had to go back to manual focus, but only with focus peaking available of course (which reflects contrast rather than true focus and changes accuracy with contrast level). I got on okay, but lost a few takes in AF before I twigged, and it’s not what’s expected in a current model camera.

Service

Panasonic can't supply a replacement base for the FZ, even though it was the current model when it went in. Seems I have to bin that camera now due to lack of support. Their quote is nearly $400 to replace the mount on the broken 14-140, a $600 lens. The camera store has offered me a discounted replacement, currently pending a figure. The first time the FZ went in, it came back with a thumb print on the sensor, so had to go back for a 2nd try.

Credit where due, Nikon here have been fantastic with pro support when I've needed it, really bending over backwards to help, although that hasn't been needed for years now. Undecided at present whether I'll bother with the D7100 - it has probably earned its retirement. I bought another pristine D200 for $172! The Lumixes haven't earned their retirement yet...

This has been a tough assignment for the cameras, and a small sample, but maybe of interest to this discussion. I can't say if a pattern is emerging.

P.S. I also used one drone, a DJI Phantom 3 Professional. It did many, many flights, almost daily, some through smoke or dust clouds from machinery, and it never missed a beat - a real workhorse.
