Epub is probably your best choice of format as even the Sony store will be moving to that format by end of the year.
I mostly use Calibre to manage my books but if you ever purchase books from Sony then you have to use that software to buy the books (you can then add the books to Calibre). Also, if you plan to borrow books from your local library, you have to use Adobe Digital Editions to initially download the book.
I use ADE to manage my borrowed library books, Sony for any Sony offered freebies and Calibre for everything else. It's not that difficult juggling 3 different software programs.
