My subscription for IPTVX ended, and I decided to try out UHF instead, having read good things about it. It seemed to be better supported than IPTVX, but more importantly, it offers a one time payment option, even if it's steep, which I'm fine with (you get what you pay for).
I'm pretty sure I'll be continuing to use IPTV for the next 5-10 years. It's been nearly 8 years since I started using an IPTV service!
Even if it's only been two weeks since I started using UHF IPTV, it's been fantastic. A quick interface, no waiting 1-2 minutes for the playlist to load every time, and a good amount of customisation offered as well! Most importantly, it has full support for all HDR types.
I tried keeping an Android box alongside the Apple TV for Tivimate, but it was a pain to keep switching between the ATV, which is superior in every aspect except no Tivimate, and the Onn 4K Pro, which was just used for Tivimate.
I ended up giving the Onn box to my parents, who greatly appreciate it.
So I'm quite happy with UHF IPTV, and I hope it remains a stalwart option.
