If you are into the political debate, Apeks/AL is French owned. ScubaPro is US owned. For some it an issue to spend money supporting a US company to booster the economy, ie Johnsons Outdoors vs. AirGas, during the economic down turn in the US.
Correct me if I'm wrong, but as I understand it, Apeks and aqualung are not the same company. AL is just the US distributer of Apeks. Apeks is a brittish company,
I use apeks because I like the simplicity of the DS4 first stage. I dive cold, so I wanted an environmentally sealed diaphram reg. The DS4 is fairly stripped down, with only 3 LP ports and 1 HP. It is small and compact. I believe the MK25 is a piston that would need to be environmentally sealed to dive in very cold water. When I was choosing regs, I had not heard about the MK17 so I didn't consider it. Another thig about Apeks is the DS4 firsts that I like can be had fairly inexpensively. I found an online retailer that sells them for about $150.
I do like the by US argument for SP. If I had thought about it when I was buying regs, I might have gone with SP. Something to consider when I can afford to by a dedicated singles reg, rather than using the same regs for singles and doubles and switching hoses around. I just got my doubles setup completed, so I haven't fealt the need quite yet. I do like only having one kind of reg, so I'll probably stick with DS4 XTX50s, but I'll at least consider MK17.
Can't really go wrong with either SP or Apeks. Never heard any complaints about either.
