I don't think Sony had 48" 2021 model... only older 2020 for much more than c1Gradients are not good on lg in general, that's their main downside atm. Sony has great gradients, so maybe next year see what sony offers if that really bothers you. Although, Sony's motion is currently worse than LG so, trade off.
I hope Sony can match LG's artifact free motion interpolation on c1 and match 2017 sony tvs in smoothness, because they've gone backwards. I'm less confident that lg can fix their gradation smoothness.
