Experienced BMX rider, I need help choosing between these bikes...?

[grace_cochran]

I am really just starting out I've only practiced on my friends bikes and I'm buying one for myself, I will be doing mostly flat land and park riding, and I am having trouble deciding between these two bikes (in craigslist adds with pictures) I don't know which one will be better for the stuff I want to do.
Please help?
