If cost is not really an object, then I would select your training platform based on what type of airplane you expect to be flying in the near term.

If you're going to be flying a new-ish twin like a G58, then you probably want something which has more glass and technology for training (DA42, new seneca/seminole). Best to train on the same GPS that you will be using, if you know or can guess.

If you even think you might be flying an older steam gauge airplane then train on a duchess or an older piper. If you are used to glass and get in an analog airplane, it could be fatal if something goes wrong.

If you don't know if you'll be a flying a glass airplane, train on analog. It's easier to go analog to glass than vice versa.
