I'm delighted with mine too. My mate has the Zeiss FL 7x42s and we swapped bins in a hide last week at dusk watching streams of starlings fly past the sunset to their nearby roost at Meare Heath in Somerset. His had a wider field of view and were a tad brighter (but not much) though no sharper. What's more, the eye relief wasn't as good as on my Swifts and even with the eyecups fully extended I still had to hold the Zeiss's slightly way from my eyes to get a decent view. So, for me, overall my Swifts, with the twist-up eyecups and which I bought about 9 months ago from Ace Optics in Bath after trying several different makes, were definitely preferable. He wears specs and so turned the eyecups right down and was certainly impressed with my Swifts too (and wasn't just being polite). The new diopter setting is also excellent. Once adjusted, that's it, no further need to fiddle ever again unless your eyes change. Price difference around £600 - £700. Frankly, I have no desire to upgrade, but so far I've yet to meet anyone else with a pair. Everyone else seems to have Swaros, Zeiss, Leicas, Nikons or Opticrons. I've looked through most and not been convinced any of the premier makes are worth the huge price difference. In fact for me some have been, for one reason or another, definitely inferior to my Swifts. But bin choice is a very personal thing and you should always try before you buy as there is significant variation even between the same models.
