I would say that there is not much difference, at least here in AZ. All new grads start at the same pay, regardless of education. When I am done with my current nursing program, I will have an associate of science in nursing and I will start with all the MEPN graduates at the same pay while having paid about 35k less for my degree. In fact, in Tucson the Pima Community College nursing program graduates have a much better reputation in the nursing community than the MEPN students in terms of being better prepared. And some find having a master's degree in an area where you have no real-life experience as an insult (NOT saying I feel that way, but I have heard this from many already in the nursing field).
Also, my prior bachelor's degree is in social work and I worked in child welfare for 10 years! Small world. Anyway, for reference, I applied to and was accepted at the Pima nursing program, the MEPN at the UofA, and the traditional BSN program at NAU in Tucson. I ultimately chose the Pima program because of cost (less than 10k vs. 45k and 25k for the others respectively) and the reputation of the Pima program. I know I couple people in the current MEPN cohort and the cohort which just graduated in 2019. I have not heard great things. But, plus side, you do get done quicker. I am very happy with my current choice! Also, I dropped the GCU concurrent enrollment because I found a more affordable option through NAU. After completing my ASN degree through Pima, I plan to pursue the online MSN through NAU which is available to those with a non-nursing bachelor's degree.
Good luck in whatever you choose! I also recommend getting started on nursing prerequisites asap. They took my 1.5 yrs, plus the semester of applying to programs, which means there was 2 years between me deciding to go into nursing and actually starting my program.
