And aside from brightness, they have very similar performance.

Not even remotely.
...what about the 10500 and 5040UB?
Again, not even remotely.
Do they all have the same performance??
When they're really similar, they have very similar performance yes. Lets go back, the Planar 8150 and all the LED DLPs based on the same Delta platform all have very, very similar performance.
No. Stop comparing the UHD65 and the UHZ65 especially when it comes to light loss! You're comparing the light loss of a bulb projector to a laser projector! Doesn't correlate.
It's as good a guess as any, at the very least the odds of it losing a ton of light like the UHD65 is about equal to the odds that it won't lose much of anything. That said, knowing Optoma's history, given that the UHD65 and UHZ65 seem to be based on the same Coretronic platform IIRC, I would have to assume their brightness performance is quite similar.
But lets look at it this way, if it loses only 20% when calibrated, that would put it at over 2200 Lumens. That makes it significantly brighter than the Sony VW885 ($25k MSRP) and nearly as bright as the JVC RS4500 ($35k MSRP). Sorry but I have a hard time believing Optoma, in a budget projector platform, can hit those kind of calibrated Lumens. Especially not when the RS4500, which is in a much
larger chassis is gets very loud when run in high lamp to hit its specs. It seems far more likely to me that their using a filter setup much like the UHD65 that it quite a ways off D65 but much brighter that lets them claim such high Lumens.
Either that or it will be at even more terrible contrast since you're looking at business-class machine brightness and cost there.
What do they say, when it sounds too good to be true, it usually is. $5000, Laser, "big iron" (RS4500, Lumis, DPI, VW1100) brightness, Home Theater image quality. Something just doesn't add up there.

A 4K Sony with lamp has better blacklevel, but in nearly every other aspect it's not on par.
The SXRD panels degrade over time, the lamp ages and needs replacement every 1000 / 1500 hours.
It's not completely dustproof.
Neither is DLP, you'll find folks have reported dust blobs with DLP. It's rare, but it happens. The same is true with LCoS, it's rare.
I currently own a JVC X5500 / RS420 but my next will be a bright laser DLP.
Having a high end (higher end than any of these XPR machines) DLP hanging in my HT, next to my RS600, I think you'll be disappointed with that move.
