As we know, the manufactory is the only one to have only 4 base yields (all production), while both the academy and the town are at 6 (6 science and 4 gold, 2 food, respectively). Might be the reason the manufactory seems so underwhelming, especially compared to the ability to instant-build any wonder of the early to mid game.
Expanding on GP tile improvements more, I think the academy is the only one to receive +3 yields from its tech scaling, while the others receive +2. I'm not sure if that's needed after the science rework, but we could also bring others to +3 instead of nerfing the academy. We could also leave it as is if that's fine, I guess, but I'll always have the itch because of the asymmetry.
Oh, by the way, it's worth to notice that the town's base yields can easily be brought up to 10 (not counting scalers). +1 gold and production for being on the road and just as much for having a caravan passing over it. Something to keep in mind. At the same time, I can envision Funak coming in with something like 'But their instant ability is so good that I don't build towns anyway!'. That's true - 20 turns of WLTKD in all cities is nothing to sneeze at and can easily cause perpetual WLTKD towards the late game. For what it's worth, I think cutting the duration a little would benefit the subsequential balancing of the town (shall we decide it's needed).
Bottom line:
*manufactory desperately needs a buff;
*either cut scaling on academies or buff the others (might be unnecessary);
*great merchants, both their tile improvement and the instant ability, are possibly in need of a nerf.
