The 2 aircrafts are very different indeed. T-2 is fantastic to train on carrier landing. The Harrier is a more advanced add-on and requires a lot of practice. You can't be disappointed with Razbam add-ons in my opinion.
I carrier qualified in the T-2C. My friend who launched off the cat in front of me accidentally squeezed the mic button on the PCL and broadcasted, "Holy shit!" as he went off the pointy end. He had to buy the LSO's bottles of Vodka. Hahahahaha!
