It would probably be odd if someone owned both those lenses, IMHO, with less than a stop between them.
When I had the FA 31mm, I never shot it at 1.8 because it also "glowed" and had tremendous CA wide open (but IIRC didn't fringe as bad as the 77). Of course, the FA = AF (palindrome) and smaller and lighter.
The Kerlee 35/1.2 has aperture click-stops (when enabled) at 1.2, 1.4, 1.6 (unlabeled, but midway), 1.8, 2, 2.4 (unlabeled), 2.8 etc. so "stopping down" to 1.8 is easy enough. Honestly, I wouldn't use this lens wide open unless I really had to, just like the FA Ltds. The DA 35 Macro Ltd is an exception to that... and an unfair comparison for any 35mm IMHO.
