The UDP tracker is better optimized and puts less strain on the tracking server, however it is not supported by all BitTorrent clients. On the other hand the  tracker is supported by all BitTorrent clients, is more reliable for ratio updates, but more of a strain on the server. Neither tracker has any effect on transfer speeds, except that if a user wanted to use a web browser (transfers via HTTP) then the UDP downloads would not be as affected by the increase in local traffic.
List is subject to changes. Other clients may add support or the existing ones may drop it. Please refer individual client's manual/help/support for more information.
