Community vs University is the age old "town vs. gown" debate. As most such debates, there truly is no "right" answer.
For me, what was important was a solid training with numbers that will have me well prepared for general practice. In addition to numbers, I want to have an in depth exposure to all the sub specialties of ob/gyn in order to be as well versed as possible in all the procedures, as well as be able to handle what walks in my door, especially if a referral is not immediately available.
In that context, a community program makes sense. Typically there are higher numbers in both Ob/Gyn, and no fellows to fight with for cases. Lots of responsibility and independance from day one.
On the other hand, if I wanted to practice in a more academic setting (ie in a big city, within a teaching hospital), or go onto a fellowship, then a University setting would make more sense. More teaching, lighter case load, research emphasised, etc....
Anybody who makes a blanket statement such as "community programs are usually second choice" or "stay away from community programs" is quite frankly an idiot. clearly they have no interest in deciphering what the needs of the applicant are, nor do they have any interest in directing the student to the best program to fit needs. they are providing advice based soley on the bias they hold, and advising based on what they think you needs should be. pay little mind to people such as those....
bottom line...go where you will fit in, and where your needs will be met. Not sure what you want to do? Well, then go where training will be broad and deep, and give you the opportunity to do whatever you want....but, best to have an idea (ie fellowship or no fellowship) to give you some direction.
good luck
