Gonna get killed!

You all are going to kill me but I must ask, I tried the pmdg 737-600/700 and it was nice but what makes it so good I would rather fly the moach 737 maybe cuase Im used to it and I didnt have much time to fly the PMDG one at my friends house so I really didnt get to see a lot of the features of it. And maybe cause I'm just not used to payware but what makes it better. Dont hate me
I want to learn the diffrence.
