I think curriculum is one of the most important things to consider when selecting a school. Most schools only have one curricular track (w/ the exception of LECOM-Erie, OUSCOM, and perhaps others I'm not familiar with), so pay close attention to curriculum when you interview. PBL gives you a lot more independence in your studies, while lecture gives you more structure. Make sure you know your learning style well. If lectures have always worked for you, then stick with lectures.
Important things to consider in choosing a lecture formats: 1) How many hours of class a day? 2) Is lecture mandatory? You want to make sure that you have time to study, which may mean skipping lecture to go to the library at school that have 8hr lecture days.
If you are curious about PBL, I'd recommend one of two things: 1) Look into schools that incorporate some PBL into their lecture curriculum, so that you get a little bit of each. or 2) If you choose a school like LECOM, start out in the PBL, b/c as mentioned, seats are usually limited in this pathway. Switching out is easier than switching into it. This also has to do with the fact that PBL takes some time to get used to, so if you spend a couple of months in LDP, it may feel like fish out of water changing to PBL.
