telnet because it's more customizable than any other client

Bearshare is the best Gnutella client I've used... the only thing i disklike about it, is the somewhat annoying animated bear. On the contrary, if it was a picture of a real bear I'd not be bothered...

Cabos is the only client that completed downloads on my system in less than 20 minutes

I have used or tried most clients out on the net for p2p networks.
I first tried kazza, it worked fine until it got shut down. Some minor bugs in it. but hey it worked. Then I went to shareza same thing new gui interface and multi-network capable. Worked fine with verison 1. But that all changed when they updated the software. It went to hell in a hand basket, never could download anything without it be fake or corupted in some way. Then it was bearshare nice program hated the interface and all the silly pop-ups wanting me to upgrade etc. Now I'm useing limewire 4.9.23. the latest on the net. DL's run faster than anything I ever got on shareza or kazza. etc. The other night I was dl'ing a file and it was almost 200KBPS transfer rate!!
Now show me a client that will give that to you for free! And even tells you when an update is out and lets you select what type of update you want.
In short Limewire is the one I will use until something comes along thats better..

i get 300-500kb/sec on IRC easily.

Is TrustyFiles. It does have alot of negatives (very persistant popup ads - my poor adwatch is exhausted), and it went through a period of time when it kept closing after opening, then suddenly cured itself. The positive is that it connects to 4 Gnutella networks (Bearshare, Emule, and 2 others), and I was able to find things I couldn't find anywhere else.

The negative about sharing on more than one network at one time of course is the sacrifice in bandwidth & affect it has on other networks. There's at least one network where you can only downld as fast as you upload. Then if people are uplding from you one one or more networks, what happens to people on the other networks you're connected to? They suffer!!! They either can't connect or get incredibly slow downlds from you. That's why multi-network programs tend to not work so well whilst they allow multi-network connection at one time. On Gnutella, I'm sure most people would be aware how slow & unreliable Shareaza (Raza) can be. This also applies to the others such as morpheus & Gnucleus, etc. This is not an opinion, it is fact. If these programs only connected to one network at a time, then problem solved. (else dedicating a minimum of 5 KB/s per upload slot per network connected to at the time might work if there's the bandwidth to allow this.)

I love limewire it's by far the best p2p network i have tried i tried pro and went back onto the free one tho i hated how it looked and it was too complicated.Apart from the viruses on programmes the child porn,the youv'e won and the dancing girl video it's perfect.

1. LimeWire
2. FrostWire
3. Morpheus

I, for my concept, use the giFT plattform, it's very easy to use and connects to the nets that it has plugins for, it is so efficient, GNU and GPL licensed, no crapware, no ads, no PRO version (only one free version), it's excellent, for now, i'm connecting to G1, G2 Aresnet and OpenFT
