While I understand the benefits of Copa and connecting through PTY, I'm quite happy with Air Panama out of Albrook.
Firstly, Air Panama is a nice little airline. Secondly, as others pointed out, I like Boca how it is, without mass tourism. Thirdly, just a runway extension won't help in terms of weather. Currently, there's ILS at Boca, which means that there can be significant delays. Air Panama is good at re-shuffling flights, so you usually get to your destination within the day - but I would not want to risk a tight connection at PTY.
