Kram,
I have no idea which would be best - I guess it's just whichever you fancy. Personally, I'd go for the 737 - if I wanted to fly an airliner with a joystick I'd do it at home on MS Flight Sim
But that's my personal preference.
The main reason for posting, though, was to tell you to ignore those jealous idiots who are telling you not to waste your money. Guys, just because you've chosen to enter a profession where you need to get yourself into debt to become qualified, and once you're qualified you stand very little chance of ever becoming rich, that doesn't entitle you to question the motives of others who have made a different choice. Kram obviously has the desire to learn to fly big jets. But money is clearly more important to him than flying. Based on those priorities, he's made the choice to not enter commercial aviation, but to keep his current career, whatever it is, and enjoy the financial benefits. These financial benefits include doing something which those of us who have chosen less well-paid careers will never be able to do - get a type rating on a large jet purely for fun. Time after time we've seen posts on this forum, recommending to newbies that if they want to become rich they should not become a pilot. Now here's someone who's followed that advice, and we're criticizing his decisions???
Kram, to me, doing something I love for a living, rather than sitting behind a desk bored out of my mind for 8 hours a day, is more important than being rich. You've obviously got different priorities - well done on sticking to what's right for you, and good luck with your type rating. In fact, I'd love to see a post describing how you found the training once you've completed it.
FFF
