I like the Battle Factory, since you get to rent Pokemon, which is much easier than having to train your own. It allows you to use Pokemon you've never used or have only used a few times, which allows you to gain battle experience with a whole variety of Pokemon.
I think the music in the facility is interesting, it really suits the atmosphere of the Factory, in my opinion.
Also, I like it since it tests your knowledge on Pokemon, as you need to know about the strengths and weaknesses of different Pokemon, so you can rent the three best Pokemon they have for you to choose from. You need to know about Pokemon to decide which moves to use on which Pokemon, too.
