Other Best IPTV boxes

I am wondering if there will be a new wave of boxes coming out which will be best suited for IPTV. At the minute I still find a E2 sat box the best as I can record and watch FTA satellite without having to stream.

I am having good success with the zgemma H.S, its a good picture, quick to run IPTV but doesn't seem to have digital optical audio. Can anyone recommend a few boxes thats on par with this box and has the optical audio...

Mutant HD51 4K. its the box id buy if i was buying a new box

Yea my friend has one of those, really good box but expensive...

cheap compared to the VU boxes

Im really just after something on par with the zgemma HS speed wise and that incorporates digital optical audio as no zgemmas have these...
