Normally, I would recommend playing each of them. If you can do that, you will be able to tell, pretty fast, which one feels best to you.
If that’s not an option, go with the one you think looks the coolest. This matters more than you might think.
Ultimately, you want three things from an instrument, sound, look, and feel. If you can’t put your hands on it before you buy then go with the one thing you can go with. If you like the way it looks, you will want to pick it up. If you pick it up, you’re more likely to play.
None of them are a bad option and all of them have been used by people to complete course. They are comparably priced with similar features. The only real difference is going to come down to personal preference. So, get the one you think is cool.
