You should narrow the question down to what styles are available to you.
This. Style differences are entirely a matter of academic discussion if you don't have a choice. Even if you do, don't expect that as a beginner you will find the differences really meaningful. It's not like buying a car, where you know what a car is and what it does and can make some intelligent decisions about what features you'll like/need, even if you've never owned one before. For a beginner, aikido is a new experience, conceptually. You can look at the brochures of the different models all you want, but it won't tell you much.
