Engineer The Kowa is the choice. The 663 is a good ED spotter and takes a range of excellent eyepieces.
The 27x LER and 30XW eyepieces are superb on this glass. The Kowas will also score higher on a resolution chart than the Vortex.
Kowa generally, supports their products and you'll be likely to get it cleaned and repaired 10-20-30 years from now. Vortex? May not even exist by then.
Maybe another factor to consider is resale value. A 20 year old Kowa will bring as much a 4 year old Vortex on the used market.
I have a TSN-773 and it is superb.
The birding community love Kowa scopes, and they know more about potting scopes (in general, of course we have some experts) than we of the shooting community.
What sort of tripod are you using with your 773?
A lot depends on what style of shooting you intend to do. If you are only going to shoot prone, a spotting scope stand would be your best bet. Ewing, Creedmoor, First Strike, Freeland are a few to look at. These allow you to position the scope close enough to you without having to move out of your shooting position to look through it. If you are only shooting off a bench there are bench mounted spotting scope stands that clamp to the bench.
I have no doubt that the Kowa is the better option BUT!!! there is quite a difference in price. The Kowa cost more than my first car, WITHOUT the eyepiece that is purchased separately. If you’re a “Birder” and want to see the colours of the Hummingbirds eyes, then the Kowa is the way to go. For looking at holes in paper???
