XL2540 vs XL2546 vs Wait for 0.5ms AUO monitors

[zivko]

Im getting really impatient and im considering buying XL2540 or XL2546.
I plan on using monitor at 182hz with blur reduction, cause i can maintain that fps in games i play and cant maintain 240hz (overwatch mainly, i average around 270, but i still get lows in 230 and 1% lows in 190fps range when benchmarking with msi afterburner while playing).

I would probably prefer XL2540 since cheap amd card + nvidia card hack still works and i could use freesync in games i cant run at 182fps, unless the difference in crosstalk is big enough to justify going with XL2546.

I will keep the monitor as a primary gaming monitor for at least next 2 years, probably more like 3.

Do i get one of the zowie monitors (and which one) or do i wait for 0.5ms monitors?

I can afford to spend up to ~600€ so both monitors are in my price range and potentially msi nxg251 could be too, but i really like feature set on zowie (black equalizer, color vibrance, ability to set motion blur reduction anywhere in 120-240hz range) and im a bit tired of waiting.
Also, the fact that we dont even know when the new .5ms auo panel monitors with 240hz are coming out, if any of them will support ulmb at higher then 144hz and the fact that on current g-sync monitors you cant set ulmb anywhere in range they support but only at fixed values (like 120 or 144) is also making me rethink waiting for them since im gaming on 75hz montitor atm that is way too blurry for overwatch...

Pls help me decide.

Maybe find a decent monitor on sale, at least to try out, and resell it later.

Buy now because of black friday. And the 0.5ms 240hz reviews will say how are they better.

0.5ms monitors are starting to have webpages now. Prolly will be some for late 2018
