Looe is my personal favourite and I highly recommend you do that one the scenery is fantastic and it has a real traditional branch line feel. Not sure if there's anything interesting in Looe itself so you might be best just doing an out an and back trip.
Looe is a lovely place for an hour to wander around.
Locals avoid Newquay especially in summer as it gets overrun with yobs on drinking holidays.
As a local my preferred lines are:
St ives
Looe
Falmouth
Gunnislake
Newquay.

As another (ex) local, but my heart is always there, I'd agree, though I avoided the Newquay line as the service is poor especially with connections to and from the West.

Train service is poor now, and for most of the year run with one dmu so timings are not good.
I think Newquay is best out of season!! There are always a few 'die hard' surfers in Winter these days!! Beautiful coastline and beaches. Nice for a bracing walk! Spectacular in a storm!! (Nice to have a car as a refuge from the cold & hot soup!!) Headland Hotel do storm watching Sunday lunches.
Non tourist shops are still open.
Having done the Newquay branch, as other posters have said, depending on connection times you may have to wait for a long while at Par station, which doesn't have a cafe (or even a vending machine) or any sort of amenities. The village is also a long walk from the station (and I don't think there's anything to see in the village either!)
Last time I was in Newquay, I watched a very large catch of crab being landed, and a couple of very large seals swimming in the harbour. Unfortunately, I was driven by car to Newquay on that occaision. It has been a very long time since I have ridden the Par-Newquay line.And last time we were in Newquay we had a spectacular show of dolphins off the headland.
Which was nice.

However, if you really want to visit Newquay, catch the Western Greyhound 527 bus which departs from Trinity street in St Austell every hour.
I'd also recommend the Falmouth branch because there's a lot to see there. If you get off at Falmouth docks you can either walk to Pendennis castle or to the docks themselves. Since Falmouth's a deep water harbour quite a variety of ships can be left there - the last time I visited I saw a Norfolkline ferry and a RFA landing ship.

All the Cornish branches are thriving, a real success story for the rural railway.
