There was a recent thread about this, and I think the consensus was that this only really matters if one is going into Academia or the natural sciences. Do you think that this applies to all fields?
I’ll try to find the thread.
My best friend’s father was vice-president of a corporation in Silicon Valley in the '80s and early '90s, and did a lot of the hiring for the company. I recall him telling me that when he saw UoP on a resume, it went straight into the trash.
A second vote for the above. UofP is a good place to get a diploma. From the people I know who have gotten a diploma there, the education is reasonably good. It isn’t a diploma mill or mail-order diploma. But, it doesn’t have much of a reputation for education. Many jobs are just looking for a diploma and experience and for those UofP works. For those jobs where they will compare candidates based on their education, UofP is way down the list. Partly unfortunately to their own success. Most everyone knows about them. Lesser known online schools might slip in under the radar so to speak.
Which is better, the GMAT or GRE? Or are they like the ACT and SAT, with not much difference and colleges accepting both?
Most programs will only accept one test, and it varies by specialty. For MBA programs, you’re looking at taking the GMAT.
GMAT seems to be mostly business oriented, for MBAs. A GRE can be used to apply to a wider variety of graduate programs (and vet school).
Is UF too far from you? 
It just now popped in my head that I equate a Masters degree like updating kitchens and bathrooms to sell a house. The smart reason to update kitchens and bathrooms before selling a house, isn’t to make money on the upgrades… it’s so you don’t lose the chance to sell the house BECAUSE of the lack of updated kitchen and bathrooms.
For me personally, I got my Masters… not to make more money, rather I don’t want to give my next employer yet another reason to weed me out of a stack of potential candidates.
What’s funny to me is that I can’t count the number of times I was then asked if my employer was going to pay me more. 
Does that really happen? It never has with me. Once your pay is established, that’s pretty much it except for EOY performance increases.
Many, many employers have salary differentials based on education. At my job, there are 2 of us that do the same exact job; I make more because of my MA. Granted, I’m a teacher; but it’s very common in business and industry as well.
If I were a single gal without a full-time job in her career field, no. Alas, I have stuff tying me to Orlando(ish.)
