OK, so this is my opinion. I go to LECOM, but I'm in PBL, and I like it a lot. That said, if the choice was LECOM LDP vs PCOM, I'd probably choose PCOM simply for the better lifestyle. Be sure that you also know what you're getting into at LECOM in terms of the rules. They are strict, and clearly laid out, so keep it in mind. That said, if you like LECOM go there, if you like PCOM, go there. Wherever you think will make you happier, go there.
In terms of opportunity, PCOM is more well known, especially in the Philly, NJ, NY metro area. You also have the opportunity to rotate at a good amount of big sites in Philly and you are living in a big city, whereas Erie or Greensburg are more like small cities/towns. That said, LECOM has a bunch of rotation sites in Ohio and UH is one of our "big name" academic sites. Really though, Ohio has a ton of residencies and they tend to like DOs, so you'll probably be able to match somewhere in Ohio no matter which DO school you go to.
Price is a big deal. $10,000-$15,000 extra a year is a lot to swallow, especially if you are doing it all on loans. Ultimately that extra cost with interest will probably end up being around $80,000 extra by the time you pay it off.
All that said, no matter what you choose, don't look back. The grass is always greener, and no matter where you go, you will have times that just suck. The last thing you want to do is think, "if only...?" and let that bog you down. Once you make your decision and start, forget everything else.
