UK user — TiviMate on Firestick is my primary setup. ClearWave works with the Xtream Codes connection. Catch-up works perfectly. EPG is accurate to the minute.
IPTV Smarters Pro on a Samsung Galaxy phone — excellent for on-the-go viewing. Login is stable and does not require re-entering credentials after app updates.
Ireland — Smart IPTV on LG webOS TV. Setup via MAC address activation on the Smart IPTV website. Took 15 minutes including the activation wait time. Works reliably since.
XCIPTV 4 on Android TV box — the 4K HDR streams play without any issues. Channel switching is noticeably faster than IPTV Smarters. Recommend for Android TV users.
Australia — OTT Navigator on a Chromecast with Google TV. The VOD interface in OTT Navigator is excellent. Browse categories clearly. Much better VOD experience than TiviMate in my opinion.
Canada follow-up — tested on a newer Firestick 4K Max versus an older Fire TV Stick. The performance difference is significant on higher bitrate 4K streams. If you have an older stick, an upgrade makes a real difference.
