Depends on your priorities:
-> Maximum motion clarity with minimum strobe crosstalk?
-> Best colors?
-> Lowest lag?
-> Brightest images?
-> Console compatibility or not?
-> Ease
-> Vendor compatibility (NVIDIA only, or vendor independent)
For
lowest-lag strobing, it's hard to beat 240Hz DyAc on XL2546. For 144Hz strobing, the XL2411P has among lowest lag but you must tweak a lot more (harder).
For
minimum strobe crosstalk, using low Hz strobing on high-max-Hz monitor. Hard to beat 85Hz-100Hz ULMB on a 240Hz G-SYNC monitor
For
brightest strobing, you want voltage-boosted strobing. They are more common on 240Hz monitors (both DyAc and ULMB)
For
ease, NVIDIA ULMB is hard to beat since it's an ON/OFF setting
For
vendor independence, you will have to find something other than ULMB which works with NVIDIA GPUs only
For
console compatibility, I like the BenQ ZOWIE XL2411P + single strobe using Blur Busters Strobe Utility
For
best colors, a strobed 1440p IPS monitor, or select well-tuned VA panels such as Samsung CHG70 series is excellent colors (albiet slightly ghosty/crosstalky in dark dungeon games)
So kinda a choose-your-priorities thing.
