Nothing wrong with Samsung LED/LCD TV's. Samsung sells the most TVs worldwide.
But what is more important are the options on their TV's. CODECs to play all sorts of movies from USB media etc are build in. Also connecting USB storage media is easy and reading from it is working without problems. For example Sony makes it much more difficult with less support on these kind of things. Also their apps are working fine and are updated on a regular basis. Firmware same story, regular updates (and you will need these, esp when you buy the latest blurays. they sometimes need new firmware on TV and or bluray player).
make sure you understand what you want to do with your tv, just tv signal then a normal HD tv is fine. But with current cost of TVs I would buy a 4K tv to be sure. For normal blurays you can use a blueray player with upscalling to 4K. If you want to use native 4K Blurays or other 4K content make sure you get a 4K tv with HDR. HDR is now a standard option (2017 models) on most TVs. Remember that your Bluray player also need to support 4K/HDR. If you have a good WiFi signal then normal streaming over WiFi is fine. For 4K streaming ethernet is recommended.
