BitTornado was the first client I used... and now, after 2 years or so, I'm back using it again
I think in the beginning when PeerGuardian didn't work as well as today, I used ProtoWall and it bothered me that I couldn't check emails and browse all websites... so I jumped on to new clients, some that used their own way of IP filtering. But it's funny... now when I'm back with BitTornado I see why I've changing client every 3 months and why I've tried them all (I think):
Because with BitTornado it's possible to see a lot of useful information without having to click into some menu/options/details. And it's very easy to customize settings per torrent. With many of the clients I've tried you set a default setting aaaaand then... you have to alter it all the time.
And of course, now, with PeerGuardian2 - it all works perfect!
