JMeter or The Grinder?

JMeter was my first and current choice, I haven't tried out any other applications when it comes to load testing.

I bumped into this BLog, its writer is trying to see which one is better (from the Grinder side) JMeter or the Grinder.

The reason I was a bit curious about The Grinder is because GrinderStone 2.0.1 is released, I hope I'll have some spare time to check it out.
