Short answer: I would go with the Oracle rather than a Pronto. Didn't have to think much about that! However, a TV76 is a closer competitor to the Oracle than the Pronto is.
The TV Oracle is a very nice 560mm f7.4 triplet apochromatic scope which has been out of production for many years. A number of years ago when this 'scope came out I really wanted one (but was a poor student so couldn't afford it).
The closest current TV scope would be the TV 76, which is also well colour corrected even though it is a doublet design, and has nearly identical aperature, but has a faster F ratio and shorter focal length (and the scope's OTA is quite a bit shorter than the Oracle also).
The Oracle had a thread-on dew shield, if I remember correctly, which is slightly annoying relative to other designs.
The Pronto on the other hand is not nearly as well corrected for colour as the TV76/Oracle, and has slightly less aperature.
My preference would be for a TV76, then the Oracle. I don't think I'd go for a Pronto as there are competitors out there (William Optical Megrez 80 series II, Borg 76ED, Tak FS60C/78 etc.) which offer either better performance, or better bang for the buck (IMHO). However, a Pronto is by no means a bad 'scope.
