Currently, I have a TCL Roku TV 2020 model that is amazing. I have no issues with internet speed or using the interface. I'm upgrading to the LG C1 OLED but the LG's WebOS is absolute garbage. I really like Roku, so I want to keep that OS via a streaming service. which one to buy (premier, ultra, stick)? Is there any internet speed difference between a Roku TV vs a Smart TV running Roku? Anyone else using Roku on their OLED can offer some advice/cautions? Thank you for your help!
