First of all, an education isn't wasted at all. It's still going to follow you both within, and outside of the military. It will be something that you have already accomplished.
There are plenty of personnel across the entire DOD that have degrees and that are enlisted. I could point to quite a few seriously bad-a mf'ers that would take rather serious offense to that commentary, specifically that a degree is wasted as enlisted. Having been at the hip of an officer for literally everything for a little bit of time as a platoon RTO.... there's nothing a LT actually does that requires a degree. Does some college level english help with doing paperwork? Yes. That's about it though, and I read/helped/proofread everything that my LT did, just because he wanted a second set of eyes to make sure stuff was done right the first time and wouldn't get kicked back... You will get taught through whatever program you go into either enlisted or officer, what you do/need/must know to do your job. Everything you know from elsewhere can help, but generally is semi-esoteric.
Now, having gotten out of the way, this would be a huge personal decision. If I were in your shoes, and this is speculation and expansion upon it therefore could be utter and total horseshit.... Education is easier when you stay in that mode. You're used to homework, you're used to the environment, you're used to how things are done. Shifting from that type of environment into the military with it's completely different environment is a huge shift, and while thousands of veterans (including myself) are in college post-service, I think that it would have been "easier" for me to just have gone HS->College->Military than what I have done, which is HS->Military->Civilian employment->College. Being honest, I'm only in college because I can, not because I really ever have wanted to attend college. Effectively just blind hope that I learn something useful I can leverage in my personal life or possibly in a business venture.
Completion of college once your are in it will give you a document and associated positive stigma with regards to employment anywhere. It also gives you the latitude to enlist later on and see if you even enjoy the military experience of your chosen branch. Furthermore, that degree IS recognized by the military and you will come in with a higher rank and associated level of pay due to it. Following that, having a degree also gives you the latitude to more easily "Mustang" ie Officer Candidate School of your chosen branch, should you enjoy the military but have a desire or drive for being in a commissioned leadership role.
So, in short, if I were in your shoes, already IN college, I would continue on with things. Especially as a junior in college. You've already taken a big chunk out of what you need to do to earn your degree, just finish it off and perhaps look at using any bonuses/etc you may get for signing once you have your bachelors and enlist, to help pay off any debt you may have from college. Then, you can use education programs to be able to come out (provided your end unit's optempo allows) with even more education as well as training and experience that will increase your marketability once you do eventually enter the civilian workforce. Everyone gets out of the military at some point...
