New TV shopping?

I am looking into buying a new t.v. My Toshiba Fire TV isn't that old but I am frequently having to unplug it and reboot it or else my apps often don't open right.

I don't want a lot of extra gadgets and I just basically want to stream shows and occasionally switch over to network TV. I am not looking for surround sound or theater quality visuals. I just want clear images and clear sound.

What I am wondering is if it's worth it to get the OLED vs the LED. There's like a $300 difference, and I really don't want to spend that much more, if I don't have to. Also does anyone have brand recommendations? So far I have been wavering between a Samsung or Sony, but I am open to other suggestions. I suspect the issue with the Toshiba is it came with a lot of preloaded Amazon apps that take up a lot of memory space, and it won't let me delete them. I had to give up Discovery Plus because it just kept crashing. I am also looking at ditching cable and switching to streaming you tube TV, but I am too scared to download anything else given the TV is already not working right. Which ever one I end up getting I will need it to be compatible with the Amazon Prime ap, Britbox, Acorn, You Tube TV, and Discovery Plus.

I have done some Googling but would really like some additional input and advice.

Also I don't think it's my wireless service thats the problem because it's only the TV I am having issues with. Thank you in advance.
