General Is it more convenient to stream media with an application or just having a Smart TV with all connect

[DenW 2]

I am just interested to make a survey about streaming media popularity and how people got used to do it (media stick, streaming app, streaming services with a Smart TV, etc.) 
Nowadays there are a lot of streaming services with the help of which we can watch movies, shows, listen to music, radio etc. with a Smart TV or just popular media sticks, like Chromecast. 
I am the person who has Chromecast, but streams media with an application and PC server (Serviio). 
What do you think, how people get adjusted and which way is the most convenient? 
Thank you for your answers in advance!

I would use a USB normally for movies but the download takes a while so I might use some favorite streaming websites using the browser. Also, not to forget Netflix and Hulu. They're also good for movies and TV Shows.
