I do not have a R1 Meopta but do have R2's in 1.7-10x42 and 1-6x24, I think their glass is great. I do wish the illumination intensity would go lower for very low light.
I just purchased a couple of Leica ERi 2.5-10x42 with 4a reticles, and have been non-scientifically comparing it to a Swarovski Z6 1.7-10x42 Plex non-illuminated.

Thus far, optically I see little if any difference. I like the Leica well enough that I just ordered two more. I am waiting for darkness now to see how I like the illumination control, as to its low intensity. It is not a bright light day illumination system, which I personally have little to no use for.

I made the first purchases in a large part due to BobbyTomek's commentary on a forum. Bobby definitely has experience shooting at low light / night, with many high end scopes. I have a few Zeiss, Kahles 30mm scopes and optically this Leica and the Swarovski are in the same class, to my eyes.

Mine was a 3-12x50/4-a, and it even outperformed the SB Zenith 2.5-10x56 in terms of low-light performance and was virtually on par with the Kahles CSX 3-12x56 in moonlight.
