what is the best emule mod

emule xtreme !

BlackBeard EMule.

been using this mod for a while now - upload kick against those wicked leechers :D

emule flux v047c-chd-0706-codename-hidden-dangerous-0706

eMule Plus

Neo Mule is also good

Nobody uses Shareaza anymore?

No such thing, dude
Every mod works differently for each other

You just have to test some mods and decide for yourself which you like the most

Xtreme is good for me beacause it has DLP
but its offical forum is German not English and i can't read it at all

Does it even have a sense to use anything beside the orginal eMule?

I tried use MiniEmule on my DL server, however it did not end up well. The compile somewhat don't like my VIA C3 CPU and the program was sometimes inactive for second or two... sucked. Now I use the orginal eMule and it happend only rarely :)
