Evilnat 4.93 CFW on CECH-2001A

I want to take the plunge and buy a PS3 to install CFW on but almost all I have seen online have FW 4.93 updates already. I keep getting different answers depending on where I look, but it sounds like I can load the Evilnat 4.93 CFW which is somewhat recent and that is truly CFW vs the HFW? Any particular online guide to follow you can recommend?

I have modded a DC, GC and handhelds but am new to PS3 ideas so any help/explanation much appreciated!!
