I remember feeling more "satisfied" after seeing AGT in 1994. Going back to the beginning, seeing Q, Yar and O'Brien was fun, as was seeing everything in the future. It was definitely a formulaic TNG adventure of the week episode, but it worked.
Fast-forward to 1999, watching WYLB didn't leave me with that same feeling. Overall I liked it, it definitely had a more final feel which was sad. I loved the montages (except for the glaring ommission of Jadzia) but the Sisko/Winn/Dukat thing bugged me so much that I can't say I loved the episode.
So to me AGT was better because it was a perfect episode for TNG. WYLB was very DS9 and brought closure to long running storylines BUT the missteps in that episode are hard to overlook.
