I recently flew two of their retrofitted 332's between Boston and Lisbon and paid for an exit row, row 25/26, along the wings. Excellent amount of leg room. Close to bathroom and opposite the jump seat FA for take off/landing. For ~$30 it was worth it. Version 3 and 5 of TAP planes on Seat guru are the updated ones, but not that accurate for row 25/26. Expert flyer seat map is better. As the flight comes up you can track which equipment you will be on and note if its one of the upgraded versions (see thread on FT that discusses this).
Food in economy was actually surprisingly good. Economy meal, but not terrible.
All 4 of my TAP flights were on time and had no issues.
