I have a Zeiss V4 3-12x44 and its a great scope all the way around. I do have a VX Freedom 3-9x50 and its pretty darn good for what it is. No problems.

I have a Zeiss Duralyt that is good, a Minox ZX5 3-15x50 that I think is really a Leica thats amazing and believe it or not a Nikon Monarch 3 4-16X50 BDC which is also very good in low light. I do have a Vortex Viper 2-10x44 and its pretty good too.

The Swarovski is on my list to try.
