So it seems to me that most of the time it is better to pop the GP rather than use it to build a improvement...
For example an academy gives 8 beakers per turn. Lets assume the city has a 100% bonus (its typically 83% with oxford + university, but lets just assume 100% for ease of calculation).
In the mid game the scientist typically gives me 2.5k+ beakers. So at 16 beakers per turn the academy would take more than 150 turns to pay off vs just popping it....hardly ideal given that this is already more than 100 turns into the game.
Engineers and GPs (if going for full piety) seem to be mainly useful for improvements though, as you need a very high production for wonders and GPs have a very limited use if you use them to spread religions. No point using them to bomb a holy city when the AI will take it back with cheap missionaries. I only ever use GPs to spread religions to friendly AIs who havent founded a religion yet, and in very large cities that missionaries arent cost effective for (or if the AI hates me and wont give me open borders).
Customs house is just lame, especially if you have full piety holy sites.
Musicians seem best for great works, as concert tours are very inefficient.
Writers seem best for culture gains mid game as at +2 culture per turn, it takes forever to pay off.
Artists are the same, golden ages are far more valuable except very early into the game.
