I have the ATX 65 and can't say enough good things about it.
I know this is apples to oranges, but the only side by side comparison I've done with it was next to a buddies Kowa 20-60x88mm
Both scopes performed phenomenally all day. 60 power comparison tied through and through; crispness, edge to edge clarity, field of view and so on. Magnification of the two matched perfectly according to the human eye.
The Kowa did however hold better visibility once full dusk set in. The Swaro was still usable, but the Kowa was preferred for the last 10 minutes until pitch black dark. Now remember that's with it's 88mm objective. I think that made my smaller and lighter Swaro shine in it's own right. There's no doubt in my mind that the Swaro ATX 85mm would hold it's own against the 88mm Kowa, maybe even outperform it. And the 95mm Swaro would outperform no questions asked.
Of the spotters you've listed, they're all top end glass. They're all going to look flawless to you, which they nearly are. You'll never be saddened by their performance alone.
Remember side by side comparisons only point out what could otherwise be considered negligible if you were looking through a lone scope. Side by sides are done just to find a foot more field of view, a half ounce less weight, or 90 seconds longer of light gathering ability. But here on LRH we tend to be optical buffs, so I'll give this ego minded answer: I think the Swaro would be the most likely to win all side by side "battles", or at worst it would tie. Ounce for ounce, millimeter for millimeter, It will not be beat.
