Hiya -- I'm a beginner too. I chose to learn outside atw's first, learning from footstall and then from juggling. After I'd become *relatively* comfortable with outsides, I tried an inside atw. The first couple of times, it felt pretty odd, but then something clicked and it almost felt *easier* to me, doing the insides. This is all on my strong foot... I still can't manage even a footstall atw on my weak foot.
All in all, it's personal preference. You'll need to learn both anyway, and then consecutive inside/inside, outside/outside, outside/inside, etc etc..., so just pick one and go with that until you're comfy with it. You have to start somewhere! Good luck!
