To say, the RF-S 18-45mm is a "better" lens in terms of optical clarity, although it's operationally less capable on paper (2/3 stop slower on the wide end and 3mm narrower).

Providing as I've personally noticed the samples out there from the RF-S 18-45 have more oomph, than the EF-M 15-45, in my eyes.

I don’t know about “more oomph” from the RF version, and I was always surprised by how well the M version performed. However the extra 3mm on the wide end is a HUGE advantage that the M version possesses compared to the RF-S lens.

That 3mm gets me to an equivalent 24mm FOV on a crop mount, as compared to approx. 29mm with the RF-S lens.

+1 - The 15-45's selling point (a decent copy) is the 24mm - equiv in standard zoom. The only equiv lens for RF is the full frame options which are super expensive L's or reported by Chris Frost not brilliant on APS-C 15-30. Or the large chunky 15-85 EFS.

The 18-45 RFS looks like a truly meh lens...... (18-150 becomes interesting for the wide zoom range, quite like the EF-M variant alongside a 11-22).

Hence 1 M6II has an important place still in my bag Long live EF-M as a perfectly good small camera system, with likely access to good 2nd hand lenses for the mid term at least.

exactly!

+1, M6II plus a good copy of the 15-45 (like mine) plus a 22 can handle most travel photography tasks!

My M6 II light travel kit currently is the EF-M 15-45, EF-M 18-150 and an adapted EF-S 55-250. This gets me from 24mm equivalent out to 400mm.

On the R7 I substitute the EF-S 10-22 for the M15-45 and I’m good to go. If I want a little better IQ, such as on an upcoming vacation to Jamaica I will be carrying my R7, EF-S 10-22, RF 18-150 and EF 70-300 L

Frankly, the only big reason the R7 is better for me than the M6II is that when weight is not an issue, but IQ and reach is, I can use my RF 14-35L, RF70-200 2.8 L and, most importantly RF 100-500L, all of which are usually in the bag with my R5
