Debating to buy Ipad or Ipad mini

Hello...
I am looking to buy an ipad for school note taking/ surfing the web/personal organization. My question predominately is if I work to use Microsoft onenote is it better to go with a mini or Ipad retina display. I plan to utilize my ipad sort of like an ongoing journal just documenting all sorts of things to just declutter paper and be more organized.

If anyone can advise me on how they fill the difference is for them that would be great.

thanks

iPad
