Lifehacker, a software weblog, took a survey of 13,823 readers' preferred BitTorrent clients in May 2015. It showed that μTorrent still maintains a sizable lead over competitors, despite concerns over adware and bloatware. Runner-up Transmission was praised for being lightweight, while qBittorrent was praised for being cross-platform and open-source, Deluge for its plugin library, and Tixati for its simplicity.[2] Vuze, another notable client, failed to make an appearance in the top five for the first time.
