There is no critial answer for the word "BEST".
In my opinion, it is depends on the user-experienced,
and the functions user needs.
For beginner, I guess the best is BitComet which
is fully functional BT clients
(such as BT download, create)
For more experienced user, the Azaureus would be the best
choice because user can modify the source code to
suit their need. Also, it is OS independent which
can be use in most OS.
However, for me, I choose BitSpirit, because it
provides a unique ADSL anti-freeze function as I use ADSL
for internet connection. I experienced a connection
slow down when I start BT from other BT clients.
Other BT programs such as BitTorrent, Bittornado
provides different user interface which might be
a choice of other BT user.
