Just looking for a budget 70"-75" TV so these two come to mind under $1k, one is Web OS other is Tizen based. To be honest I'll simply run a PS4 if needed.
It's just a spare TV for the office area so won't need to be flash.
I have a 75" Hisence upstairs I'm happy with, so I'm not picky.
Aldi you can return if you do not like it, but 99.9% chance you will not be able to return the Linsar.
As such I would get the Alsi and if you do not like it you have 60 days to return it.
