qBittorrent

For private trackers you would use the standard qBittorrent else risk a ban due to using a modified torrent client. Or at least double-check the private tracker's rules to verify that they allow qBittorrent Enhanced Edition.

For non-private general public torrenting you would still use the standard qBittorrent client unless you specifically want those additional features in qBittorrent Enhanced Edition. From their github https://github.com/c0re100/qBittorrent-Enhanced-Edition

Features:

1. Auto Ban Xunlei, QQ, Baidu, Xfplay, DLBT and Offline downloader
2. Auto Ban Unknown Peer from China Option (Default: OFF)
3. Auto Update Public Trackers List (Default: OFF)
4. Auto Ban BitTorrent Media Player Peer Option (Default: OFF)
5. Peer whitelist/blacklist

IMO if you really hate torrent peers from China that much it's much, much easier just to do a geoip ban in any standard torrent client. e.g. create a IP Filter .dat .p2p or .p2b file with Chinese IP addresses and load it into the torrent client's IP filter.
