what version has the most active servers

[stinkfist]

I came across an old HD of mine and I had stored different patch versions of Everquest in various stages of patches. Which version offers the most active servers. I need to delete some files so that I have some extra space on the HD.

6.0
6.1
or
6.2?

thanks for your input.

6.2 (working with eqemu 0.6.2 to eqemu 0.6.4) this is the last patch :)
