My Sony TV has android and is fairly responsive. Maybe a second lag, but definitely not 10-20 secs. I do need to give it time to “warm up” when I start it, though. I use it so rarely it’s generally turned off from wall outlet.
I still prefer Apple TV for various reasons, though, responsiveness being one of them.
Torrenting is easy, but what are you goung to do with the torrented files then? Without additional external hardware you probably won't be able to play your downloaded files on your large TV, and most people prefer a laggy simple route over having to do more work. I do torrent from time to time, but the hassle associated with the whole process really highlights why streaming apps took over.
Sony TVs are some of the most sane options in the TV market right now. Generally decent, and they don't fight you if you want to use them without connecting them to the internet. Still not perfect and they'll cost you more, but it's a worthwhile trade to me.
