Olympus is one stop dimmer, it's equivalent to 24-80mm f/5.6 on FF. And the weight and price, all other things being equal, is growing as f^2 to f^3. So, by that metrics, Olympus is way too heavy and too overpriced.

Better optics for the sensor though. Fewer flaws and fewer people complaining about what they're paying for.

That's not really true. A bigger frame is always a better platform for lens design - resolution can come down a bit and there is much more room for trading that off for other parameters that further improve image quality. Small flaws and aberrations are harder to detect and less critical.

Not quite the same story with those FE zooms so far. I'm still curious to see what happens when you attach that F4 zoom lens on a regular APS-C body, the results will be probably even worse if it follows the same pattern as the FE primes.

Why would you do that though? The lenses that are designed for FF have not been optimized for APS or M43 and in so many cases will look worse.
