I dont know if i could stand 30hz.. I love higher rates such as the interpolation technology offered on high end LCD/LEDs (120hz/240hz in NA and 100hz/200hz in EU) I recently got the Asus VG248QE
it works 1080p @ 144hz and I love it. Even moving a window quickly in a circle with duplicated displays one @ 60hz and the other @ 144hz it looks a world of difference! I cant wait for greater overall bandwidth to push even greater rates. Actually in a few years when 4k gets more standard @ ~150hz it would be similar bandwidth as 1080p @ ~600hz. Many would argue that the human eye cant see such detail and I agree but the higher rates i have now feels
significantly better and I believe a greater native refresh rate will greatly contribute to how insane the next 10-15 years of television technology will change.
I read a lot of reviews before purchasing the higher refreshrate monitor and a lot of the outcomes was greatly varied so its all in taste.. If i were you i would test it out see which you like more.
