Thanks guys,
I can see why uTorrent gets a lot of
s - Its a simple slick client but not feature rich enough for me. Torrentflux integrates web with a back end client of your choice which is vital for easy administration when you're out and about.
As so far as speeds are concerned it all comes down to how you configure simultaneous connects,correct port forwarding, not saturating your upstream etc. If like me you like giving 10000+ simultaneous connections then a fast machine/disks are a must.
