ULMB2 and DyAc+ has similar strobe-amplified microstutter mechanics, although there might be slightly fewer double-images with ULMB2 thanks to standing-ovation steller max-Hz strobe tuning.
Although Blur Busters Approved is good for flexibility (XG2431 can strobe 59-241Hz in literally 0.001Hz increments), I haven't seen an IPS be strobed max-Hz as well as NVIDIA successfully did ULMB2 with, thanks to its shockingly clever overdrive algorithms, which I've written about in my article.
The strobe crosstalk double images will be reduced, but the framerate-based double images won't. You'll still get duplicate images doing lower frame rates than strobe rate, that's sadly a law of physics. Duplicate images from low frame rates are full-strength duplicates (as strong duplicate image as original strobe), unlike strobe-crosstalk double images (faint remnants of incomplete LCD GtG)
That said, if your priority is great max-Hz strobing, ULMB2 is now among the best strobe technologies I've seen. That being said, refresh rate headroom is preferred for crosstalk-free purists, 100Hz Blur Busters Approved (with QFT trick via large vertical total, www.blurbusters.com/xg2431) still has less strobe crosstalk than 360Hz ULMB2. But if your priority is best quality at max Hz, it's hard to beat NVIDIA's engineering overkill on stupendously advanced overdrive algorithms. Fixing the last 10% of overdrive artifacts costs 100x more than the first 90%, and many independent manufacturers, alas, won't be able to match that.
