I agree with gunner, you can't go wrong with either. I've only used Zeiss, and I love them, but you'll probably find more guys swearing to their Swarovski's. Try them out and find which you like best. That will be the best brand for you.
Thanks for the input.I went to the store to compare today.I think I am going with the Swarovskis,they just had more clarity than the others I looked at.
