whats the best p2p program out to find rare files

i've so far used

1edonkey

2limewire "preferred program of choice"

3morpheus

4bearshare "havent really used it was angry about the stupid spyware that comes with it"

5 i mesh

6 kazaa " absolutely terrible compared to what it used to be only going downhill"

ive always tried ares warez and overnet which all three of them were slow as hell

i perfer limewire im just wondering if someone knows a program that i havent tried yet that you think will give me more selection of downloadable files

thanks
