Excellent, but...

I've been thinking about this thread in spite of the OP's limited vision. I originally assumed that the OP was just trolling looking for arguments. But the OP has a point, as does:

Many of us have thought this for years and not just for the M system but for all of Canon's APS-C cameras. Canon's best lenses are FF lenses. Canon has not designated any non FF lens as L with the exception of the Pro 1 compact (to my knowledge). I believe that Canon's philosophy is that it is a FF camera company and that all its other cameras are accessories dependent on its FF lens line. This is too strongly worded but it is the thought experiment this thread has lead me to.

This is not to say that Canon's APS-C specific cameras and lenses aren't good, many are really really good, especially for the cost. But the kit zooms are just that. The EF-S 15-85 and 17-55 f2.8 zooms are good but big and not as good as the 24-105 L or the 24-70 f2.8. So no excellent standard EF-S zoom.

IMHO the best Canon APS-C standard zoom is the one on the G1X3; both in specs, 15-45 f2.8-5.6 vs EF-M 15-45 f3.5-6.3, but also in my own testing (sharper across the field than my 15-85). I've long used G series P&Ss but I've regarded them as accessories and I think this is what Canon intends. Ever since getting my original 5D I've regarded my XXD cameras as 1.6X teleconverters for my 100-400 L. Although the 55-250 is a handy accessory. And, the XXD and 7Ds are no smaller or lighter than FF.

Until recently, the XXXD and M cameras have been consumer cameras that only needed kit lenses, but you could use EF lenses if you wanted to. Again IMHO it was the development of the DPAF line of APS-C sensors that really revolutionized the mirrorless cameras like the G1X and M series giving them DSLR equal AF speeds. The 24 and 32 MP sensors rival their FF counterparts except for higher ISO related noise. The M5 and 6 series are really excellent cameras deserving excellent lenses. But Canon has a conundrum with their M lens design constraints which limit them to excellent 11-22, 22, 28, and 32 lenses but slow kit lenses longer than this. Sigma sees the potential and I think other 3rd parties may step up. But Canon? IDK. Canon's current emphasis is on the R series development and this is all FF.

Still, in answer to the OP, the M6II is an excellent performer. It outperforms its 90D counterpart for frame rate and AF. If you relent and use the EF adapter there are many great zoom lenses available. And there is a great wide zoom, macro and a number of fast primes. Just no excellent std zoom. It makes an excellent accessory to the std L zoom on your DSLR.

I'll also show you this, a 15 image M6II focus bracket set taken hand held using the 28 macro's ring light, processed in Lightroom and stacked in Photoshop. The first image is near 1:1 and cropped some, with the little yellow shell in the foreground measuring 0.16 inches in diameter. The 2nd shot is near 1.2:1 with the long foreground shell measuring 0.46 inches. You can see the limited 1.2:1 focus range. A really good, useful lens IMHO.
