LG L1933TR vs Viewsonic VX922

[BM00]

I've been using this 19" 5:4 LG L1933TR LCD for 2 months now. I have an opportunity to replace it with a viewsonic vx922. They're both 2ms TN panels; however, the vx922 is much older than the 1933TR (tech is over a year old at this point). I'm mainly concerned with input lag...there's so many reviews on the vx922 showing it has about the lowest (THE lowest for 19") so that is a definate plus and the main reason for the question.

Worth it or not?
