If you have the time and money, always go for a BSN.
1) You never know if somewhere you want to work will hire only RN's with a BSN.
2) If you ever want to go into management, or the higher up positions, you'll need a BSN.
3) You never know if ADN will soon be a thing of the past.
However, if you get a ADN, from what I have read on many posts here, you will get to work bedside just as a BSN does. Unless you tell another RN, no one will ever know if you if you have a ADN or a BSN. (Luckily, we don't have to wear big, bold, "scarlet ADN letters".
BTW, I am going for my ADN, then plan on taking the ADN-BSN route later.
Good luck!
