Only had it a few days but am very impressed. I use the EF 35/1.4L for recording people and events where I often run into low light situations - hence slow shutters. While the EF is ½ stop faster than the RF, the RF has fantastic image stabilization. I can hand hold it quite well for indoor evening occasions.
I also enjoy the small size of the RF 35/1.8 and the way the entire package feels on my hands.
Wide open, the DoF is narrow but manual focus touch up on the R is a delight. The R detects my usage of the focus ring and instantly zooms in to my AF focus point. For people in a party, this zoom allows me to choose which eye will be my primary focus.
Macro held no interest for me with wide angle BUT now I am a convert. This allows me to approach a flower or rain drop very closely and isolate it from the background perfectly -- with great bokeh.

I like small primes. After hauling a kit of L glass, I'm ready for smaller glass. Since I manually touch up the focus often, going full MF would not be a problem. Some of those old Leica M lenses may be on my horizon!
I can certainly see this 35 becoming my primary lens while the RF 24-105 and EF lenses normally stay in the kit.
