On paper, the Orion is the obvious choice. The SVR80 is an ed doublet, ie not fpl 53, which means one can probably see some CA. At f7 an 80mm requires either a triplet or fpl 53 to be color free, or at least that's my experience.
The es scope is a triplet but not a fpl53 triplet.
The Orion is an fpl 53 based triplet, the best glass and includes a dielectic 2 inch diagonal
If I were looking for a scope to replace my 80 mm f7 wo fpl53 doublet the Orion is the only one that makes sense.

Hmm.
The old-school Celestron / Vixen 80mm Fluorite works for me.
These Vixen Fluorites don't seem to understand they are just 80mm scopes. They take crazy powers on the moon, planets and double stars.

I use a William Optics Fluorite 80, but, alas, those are long gone, I believe. My current fave? A buddy's new Explore Scientific.
