AIDA vs. Tripware vs. Tripwire commercial

[Jakub Głazik <zytek-lists () ostrow-wlkp net>]

Hi all,
I want to start one of this tools on my server but I don't know what makes the 
difference beetwen them. Could somebody familiar with this applications write 
what differs them in funcionality? For typical linux server AIDA would be 
sufficient I think?

(yeah, right, i haven't even used google;>)
