What OneWheel should I buy?

I have been riding my friends pint x every few days at uni and now I really want to get one. However, I want something good for my weight, is nimble, but has good range. I am a forgetful person so I might forget to charge it some days so good battery would help. I might be asking for too much but I wanted to see others thoughts on it. Originally I was planning to get the XRC but seeing what people are saying on this reddit is scaring me a bit. I want to be able to mod my OW and not be to limited.

Also if someone doesn’t mind taking the time, can someone explain to me what I should know about OW’s or tips to keep in mind as well as explaining what a controller is and the differences in a VESC controller vs FM controller.

Essentially someone please look out for me and give me advice. I only plan to buy one OW so I want something that’s good all around.
