Well, I dive both the MK25T/600T and the Aqualung Legend LX Supreme. They are both high performance regulators and I've been extremely happy with both.
The Titanium is priceyand not necessary. The MK25 is exactly the same 1st stage componets except for the chrome plated marine brass case.
The Aqualung is an overbalanced diaphram so it's 1st stage is a little larger and heavier.
The Aqualung costs alot more for annual servicing because you have to purchase the service parts. (The Scubapro comes with free parts for life)
If you get a new Mk25, have the service tech fine tune it. They are not always breathing at optimum efficiency out of the box.
