The CLE rangefinder patch is more like those on 70s Japanese fixed lens RF cameras (IIRC difficult to see little yellow diamond over a blue tinted field) while the Bessa 3A viewfinder is more familiar to Leica RF users. I prefer the Bessa because of this. YMMV.
I have never had an issue focusing. It has a beutiful viewfinder. If you like the field view of 28mm lenses, there is no better viewfinder for it.
