Yeah, even for the "valet" dive vacations, I take my computers & reg back to the room with me.

I went ahead and ordered the Z2 1st and second from ScubaToys. $569 and they include a free SS1, which made it a pretty compelling buy. The B2 package also includes an SS1 for $950.

I can support what the previous posters wrote. The seat saving orifice had me worried at first, but I eventually found it to be ingenious. For a quick rinse during a liveaboard the seat saver does hardly let any water in because its a thin gap (you notice when trying to suck air through it). I soak my regs for hours and then blow some air through them, and it feels like only some drops seep in (and it's just freshwater). What is a far bigger problem on any reg, is someone pressing the purge button (on any brand) and let lots of water in, or throwing the reg in the rinse tank without the cap on the first stage. Although a piston reg will still function after such abuse.
The first stage is indeed based on the Scubapro MK10, but with the HP piston seal design like in a Mk20. It has an HP seat that is rated for 2 years, 200 dives (3/300 for titanium regs), which is more than other brands. It's a very bulletproof and easy to service 1st stage overall, yet compact and with excellent hose routing options.
For cold water (below 40°F) or in very sandy/silty water, I'd seal them. But if only diving in clear, blue water on vacation, I would not seal them. Just rinse the environmental chamber after every dive, and soak and rinse them well after the trip. If you have them sealed, it needs to be done right, by a good tech, and serviced in 2 years no matter what (to prevent corrosion in brass regs).
In a nutshell, these are among the highest performing regs that breathe very smoothly, and maintain performance for long service intervals. They are very well made, and last years and years if taken care of.
One theoretical downside I see is servicing while abroad would be easier with Scubapro, but in practice hardly anyone would get their regs fixed in time while on vacation and would need to rent a backup anyway.

These brands should be lower cost than Atomics, and should also have service intervals of 2 years (but usually 100 dives). They will also breathe more than adequately. I have not tried these brands but consider them similar to Apeks which I know very well. I feel Atomic regs breathe smoother (regs have evolved to the point where performance differences in top brands are subjective personal preferences), and 1st and 2nd stage are compact and comfortable.
Second stages need service after a while as the seat wears out even sitting in storage. With Atomic's seat saver, this problem is eliminated. Someone doing only a few dozen vacation dives per year could probably get away with very long service intervals for the 2nd stage, and also for a brass 1st if not sealed. Or, as intended by the manufacturer, enjoy peak performance between the mandated 2yr service interval.
The workmanship of Atomic regs is top notch, and if taken care of I think will last longer. But these are all good regs, so it is hard to recommend one over the other. Each of the regs mentioned have pros and cons that can be dealt with. Ideally, if you tried an Atomic and felt a difference in feel and quality, that would help the decision. What I can say though is that the potential problems concerning the seat saver you heard of are more theoretical in nature.

I am often in the Scubatoys shop (they're local). Good folks and free tank fills for the one-time $35 cost of joining their Aquaholics club. 10% off across the board on all purchases too.

Agreed. That is the only real difference between Atomic regs and other brands as it pertains to cleaning.
The best practice, IMO, is to soak the regs pressurized. But, that might not be possible if the regs get "cleaned" by the Dive Op staff. How much of an actual problem this is, remains to be seen.
That's the main benefit. My regulators are all sealed, but I don't dive cold. My 1st stages are diaphragm, and the sealing is quite a bit simpler than sealing Atomic 1sts. The diaphragms seal with a flexible cover over the ambient chamber. With Atomics, they seal with the addition of christolube. That works fine, but does add some cost when the regs get serviced.
FWIW, up until earlier this year, I volunteered at an aquarium. The reg sets they used were all Atomics with unsealed 1sts, and the 2nds had the seat saver mechanism. I was probably the only volunteer that was careful when rinsing the regs. Most just put the dust cap in place and dropped them in the two sinks. They would hang up to dry, so if water got in the hose, it would likely drain out before the next diver used it. I never noticed the regs breathing wet or anything like that.
