I have a meostar r1 3-12x56 and it is the brightest scope I've owned. I've never compared to Leica so I can't say about it by it beats the Swarovski z5, zeiss hd5, kahles, nightforce that I've owned.
It's alittle big and heavy but it's bright!!!
I currently own a Meopta R1 3-12x56 but mine is a Plex reticle in the first focal plane and not illuminated. As far as for brightness and clarity i really like it but i would not have bought it if i would have realized it was a first focal plane. I didnt realize that it was a first focal plane scope until i took it to the range for the first time. I've had it a few years now and would like replace it with an #4 illuminated reticle in the second focal plane.
