The time has come for us to replace our Samsung 55" LCD UN55MU6300. Nothing really wrong with it, just want something bigger and better picture quality. Ran up to Best Buy today and noticed they had some models with A in it for 2021 and the other s T for 2020 models. In the interest of saving money I started looking at the 2020 models but having sat here bumping around the net I see a lot more "love" being thrown towards the 2019 R models compared to the T. Not really researching TVs at that time I sort of missed a lot of info and my google searches do not bring up much about the differences in the years models BUT what I have found the R series from 2019 gets the nod. Can anyone give me some more opinions here? If the 2019 is the better product and buy I probably would scour the internet looking for one.
