Axial fidelity (contrast, sharpness)? No. Not saying UO's are superior -- just that Tele Vues don't beat them.
Field-edge correction in faster scopes? Probably (though not blatantly). I recently had the chance to view the Helix Nebula via Tele Vue 32mm and an f/5 Starmaster. Awesome field, axis to edge.
Best wishes and luck.

They are both excellent, especially in slower scopes. However, the TVs have a field lens baffle not found on the UOs ("Circle T"). Finish quality favors TV, hence the higher price. UOs are the better value in a true Abbe ortho. Contrast is better for me with the TVs and a binoviewer, so I have two complete sets. I put faucet washers in my UO pairs for baffling.
I like the UOs because they share a direct lineage with my first quality EP purchase in 1971, an Edscorp 6mm Ortho.
