Some other factors you'll want to take into account are...
Will you be diving in cold or warm water.. I take it from your post that you would be cold water but just to make sure.
Will you be doing any Nitrox diving? I am pretty sure the regs you picked do take Nitrox without any further mods, but again just so that you are aware.
Lastly, the best thing is to see if you can try them out at your LDS. Some will let you rent them on your next dive so that you can see how they perform in the conditions you dive it.
I have an AquaLung Titan and I like it, and I have heard good things about Apeks, although haven't tried one yet.
I don't know if this will help but did you check Rodales site to see what they say about the models you are interested in? They may mention a feature or a detriment that may sway your decision...
