That's a loaded request, because everybody's eyes see differently. Personally, I can't stand Swaro glass. It's clear and crisp, but I can't do the bluish hue it casts across the whole view. To me, it makes it too dark in low light. So because of that, I'll never run their binos, no matter what the reviewer or the guide or the peanut gallery or the hype train says. So, to me, I don't even think the EL's are worth it. Even though I can objectively say they really are clear and crisp. But the color rendition, to my eyes, is less than ideal relative to lots of the competition.
i have never heard someone claim swaro had a blue hue to their eyes... goes to show i guess. my sig range finder has a blue hue to me, and if you see blue through any optic your are looking through to spot game, i wouldn't want it either. i tolerate it with my rangefinder because it's not an issue for the roll it plays... even a rifle scope i would be ok with it as long as it was clear, but binos or a spotter, there is no way.
to my eyes, swaro has excellent contrast, more so with EL and NL, but even SLC are great, if not fantastic with color contrast and rendition. there is something very rich about the color rendition on the kowas for my eyes too, a little softer edge than EL but same or better than SLC in edge clarity, but better color pop than SLC.
Noctivids are excellent as well, and it's been a long while since i looked through geovids.... the only alpha glass i wouldn't be content with (knowing what i know now) is Zeiss conquest, they don't do it for me at all, they are in the same category as razor UHD imo, which isn't a good place to be for the price.... i have heard people say they liked the razor uhd, i used them for a season and were the biggest optics disappointment i have had... i would rather have the razor hd myself, at least they are light, haha... went from the biggest disappointment to the biggest surprise in a good way with the kowa genesis.... i could be totally happy using those forever, though i do like the NL better and am not disappointed with them in the least, they live up to the hype for my eyes.... they took some getting used to because they were so crisp and bright, it was a strange thing for a couple days.... in a good way, but it did take some adjustment to get used to the sensory overload looking through them.
i cannot wait to glass blacktail with them this fall, though i'm not rifle hunting them this year, i'll still be going plenty with others.... hopefully my wife, but we got her a bow last weekend, so she may be archery hunting bucks too this year, but i'll try to convince her to rifle hunt
