Have both, I like the XPS2's smaller footprint much better.
Yeah - I might regret being cheap; we'll see. Even so, I bet this EO Tech 512 will be much better than the SPARC AR that it's going to replace.

Nothing wrong with the 512, but I usually have mine forward enough that the battery compartment is over the handguard's rail where the XPS isn't. Looking through them they are identical, so no real issue, just minor gripes. I would definitely take the batteries out if it will sit for a while, not sure if it the heat/shock and north/south orientation of the batteries, but even good AAs have leaked corrosive goo in mine. Luckily I've caught it, and been able to clean it out before it did any damage. Have had much better luck with NiMH rechargeable AAs(maybe sealed better?), and easy enough to charge them back up, but still leave them out when I don't plan on shooting that rifle for more than a week or so. Have had 0 battery leakage on the XPS2 with it's east/west battery position and Lithium formulation..
How about the Vortex UH-1?
Yeah I really like these holographic sights.
Do you mean horizontal vs vertical? Don't think orientation toward or away from magnetic north is going to make any difference. I've had batteries in many orientations and haven't seen different drain. Never seen Alkaline batteries leak after weeks of no use, perhaps months. I tend to use rechargeable now.
The "north/south battery arrangement" meaning AAs in the 512 are parallel to the bore, "east west" as the XPS2's perpendicular to the bore. It's a mechanic/engineering thing, not literally pointing to magnetic north. The 512's batteries take recoil force on the end terminals, the XPS2 takes it on the side of the case. Might be differences in how they are sealed, but seems seems the XPS2's batteries never leak, and last for at least a year of occasional use, the 512s AAs seem to leak after a couple months if I leave them in. I had a couple cheaper energizers leak in my bag despite taking them out, while the few unused spare batteries never have, so I think recoil and battery arrangement relative to the axis of recoil may play a role, at least with cheaper batteries. Have swapped to NiMh in the 512, but don't leave them in it out of habit, and no problems leaking with those.
