Question about ram timing

[Kitsune]

So which is better timing
9-9-9-24
or
8-8-8-21?
Also what does the timing mean, I am guessing it is pretty important but how important is the timing, I am going to be running games and 3D software such as Maya and 3DS Max.

Mainly is the lower timing better or the higher timing?

With timings, lower are better. Like latency in games. the lower it is the faster it will respond.

I had a hunch that, that would be the answer but thought I would ask just to make sure Thank you
