Utorrent is meh i used to use it but now i mainly use qBittorrent
newer versions of uTorrent are full of ads, and, what is worse is that the latest version installs a Bitcoin miner silently on your PC, which leads to heavy CPU usage and overall performance slowdown of your PC hardware.
And
qBittorrent has a decent user interface and is stable. Its memory consumption is higher than uTorrent because it is built using the Qt framework but this should not be an issue for modern PCs.
