I don't care what anyone will tell you, but they are all kind of a crapshoot. There are only so many providers for the source streams that all the IPTV providers then bundle and resell. If you are OK with quirkiness of an IPTV service, I have had good luck with iptorrents.com IPTV service. If you are not a member of the tracker, you can still get their service through their IPTV site https://privateiptvaccess.com/
