I think TolleLege nails it in post #21: if you are on the middle-to-conservative half of the evangelical spectrum and you are not looking to advance to a competitive PhD program at a secular university then you would not be particularly well served by attending PTS, Duke, HDS, YDS, etc. Although it is surely correct that many students at the aforementioned institutions go on to pastoral ministry, they serve primarily in mainline contexts or at least on the progressive end of the evangelical spectrum.
All of these terms--"conservative," "liberal," "mainline," "evangelical," etc.--are so relative that broad statements are difficult to make. However, I think it's fair to say that if you want to serve as a pastor in a conservative, evangelical church helping lay-people to better understand and apply their Bibles, then you will receive far more relevant training (note, not necessarily "better," but "more relevant") at schools like Gordon-Conwell or TEDS than you would at places like PTS, Duke, HDS, et. al.
