As you can see, they are pretty close in specs. The only selling points of the ASUS are the LED backlight and the thinner profile, maybe even the 10w less power consumption. I prefer the looks of the Samsung and its name as well. The Samsung's red LEDs also match my mouse and future HAF 932.
I am currently on a Samsung SyncMaster 997MB 19" CRT @ 1280x1024 85 Hz and the picture is absolutely great. I'm keen on the Samsung, but I'd like to be sure before I purchase.
Since I am buying in late May/early June, should I just wait for future releases (maybe a sub-$250 Samsung >23" LED) or just go ahead and get one of these for this good price?
Might be a bit late to help you, but I have the Syncmaster P2350 and it's pretty nice really. Looks great and works great.
I wouldn't have any problems recommending someone buy an Asus monitor either though since they really do make quality stuff in general, but if I was choosing between those 2 at the same price I would pick the Samsung again.
Oh I noticed the Asus has HDMI, while the Samsung doesnt. That might be important to you.
I actually have the SyncMaster P2350-1 and it is pretty good for the price. Even though I find the color a bit lacking (and those broken gradations due to it being a 6-bit panel moving from a CRT), I am glad that I did not go for the $300 LED Samsung.
