I compared LimeWire and Bearshare .
After a week of testing this are my conclusions :

LimeWire : lots of results , slow downloads , handy GUI
Bearshare : less results , fast downloads , responsive GUI

I did an sample search 8 or 9 times a night with the same keywords .

+- 2000 results in LimeWire
Only +- 1000 in BearShare
+2 MB/Sec downloads in BearShare
-500 KB/S in LimeWire .

After a lot of obeservation I noticed that my connection maxs out at 4 - 5 MB/Sec

I made up my mind .
There both staying on my system .

PS i also made my own installer for BearShare . Only 980 KB !)
But I can't put that out since BearShare would sue me .
