Changing the angle changes the effective length, so you have to take that into consideration.
Play around with this too see what I'm talking about. It's great tool for helping to decide what to try next.

That said, I don't think you should replace the stem until you've installed the bars that you want. Going from bullhorns to compact drop is a GIGANTIC fit change. You may immediately find the new position supremely comfy, or it may be too cramped, or too low. Get the bars you want and ride for a while. You'll notice what right or wrong. At that point buy a stem that adjusts the fit.
You can't fit your bike on an internet forum. Just ride a lot and pay close attention to what your body tells you. Adjust accordingly.
I prefer the upright position because speed isn't my concern, comfort, handling, and vision are. My back isn't really an issue. I prefer the way a bike steers and handles with my hands in line with the steering axis, less weight on the front wheel, mimicking an MX motorcycle fit. I ride overly long frames, chose my stems, and cut my handlebars to achieve that.
Do what works for you.
