Viewsonic XG2431 or Alienware AW2523HF for CS2?

I'm looking to upgrade from my 144hz Acer XB253Q. The 360hz Alienware monitor I mentioned is on sale right now and brings it actually $30 cheaper than the 240hz XG2431, but I'm concerned about the motion clarity of it as from what I've seen in reviews, it doesn't have any backlight strobing mode when the XG2431 has exceedingly good motion clarity even with its lowest strobing setting. I'm buying the monitor pretty much exclusively for CS2. I'm curious if anybody here has tried both and prefers one over the other or if anyone has either and has some info they'd be willing to share about their experience with their monitor. Also, taking into account I'm looking for 240hz or higher and the best motion clarity possible and not a VA panel, if there are other monitors any of you would suggest taking a look at that are at or less than ~$300 USD, I would appreciate any recommendations.

Thanks.
