This is the Australian model, so it doesn't have HDMI 2.1 and apparently there are a bunch of other things that make it inferior to the US version.
Honestly, I don't know anything about TVs and don't play video games so can't comment. Seems a decent price though…

Has 4x HDMI inputs that appear to be HDMI 2.0 and can do 4K 60Hz with VRR so not great for PS5/Series X gaming.
55" Sony X85J Refurb can be had for an extra $20 or so with Plus sale currently
