I would say being a tech is more valuable for not only your application, but for your own experience. I had 2 "pharmacy experiences" on my application. I did a summer internship (shadowing) for a total of 40 hrs. All I did was inventory, organize insurance forms, and just watch the tech's fill. I thought I knew enough about pharmacy.
After I didn't get in my 1st year, I was told to get more experience. I became a clerk at WAGs for 6 months where I also typed and process new scripts and refills, dealt with insurance claims, etc. Wow, what an experience.
Now that I looked back at my experiences, working at WAGs is what made me understand what really goes on in a pharmacy. I learned how scripts are processed, how insurance worked, how rx's are called in, how refill requests are done, how customers can be so mean, how stressfull it can be, etc.
I believe shadowing is a great start but if you have time, make sure you do some tech work. It'll give you another perspective.
