I would put my vote in for Gardiner. It seems to have more going on and a nice little downtown. A handful of independent eateries to. Lisbon is ok has a few really nice restaurants, 1 chef earning a james beard nomination but no real downtown to speak of. Look into Brunswick area as well. Lots of everything close by, young vibe with Bowdoin college. Easy travel with 295, and route 1 for coastal. May remind you more of your current location. Just my opinion, good luck.
