Should i get this scope?

I was thinking of getting the orion skyquest xt8 scope. I am only 14 years old. I've been interested in astronomy for a while (about a year), and during tat year ive been using a 70mm meade refractor. It is kinda a big step up from the telescope I am using right now and the telescope I was planning on getting. Which do you think I should get... An xt8, or an xt6.
