Of those choices, probably the XDeep. Of course, make sure you select the right BP material and wing size for your type of diving, exposure protection, and tanks. For my drysuit diving, I was happy starting with my Halcyon stainless BP and single 40 wing and single tank adapter that I seamlessly added a double 40 wing to when I started diving doubles. I’ve since started using an Aluminum BP with the doubles to reduce weight, so now I have both single and double rigs. Amazing how the gear multiplies.
Weight pouches are convenient for single tank (though if you have a canister light, the long Apeks style pouches could be an annoyance by the looks of things).
One thing that concerns me about the Apeks wing from pure observation and not personal experience is the low-profile hip dump valve, which may be hard to find with bulky gloves on and may be hard to replace if you ever need to. You will be taught to mainly use the hip dump in GUE Fundamentals, and a standard dump valve makes it easier to find the little string to pull on.
