If apps work on a smart TV then great, however if they dont, and/or the user interface on the smart TV is poor then a Roku or a Firestick is the way forward .
I own both, but my personal preference is the roku as its less cluttered and is easier to get to the content quicker, take a look at both and see what you preffer .
One key thing i would advise is to avoid the entry level model streaming devices and go for the next one up, and make sure you get the current UK ones form an official source/retailer .
Dont get rid of a perfectly good TV screen as it no longer gets the apps you want or it lags etc, get a streaming device instead and save money, and the environment as well.
