VLC players is the one I always prefer to use as they quite advanced and easy to use.
I have been using VLC player for more that 6 years and I wpuld say they are best among media players.

They support each and every format of media files so need to install separate player for separate format.
Many useful tools are available that just make it my favorite.
If your audio or subtitles are not synchronized properly then you can easily adjust and synchronize them easily.
Simple to use along with icons on the bottom part and can double the actual audio volume which is handy.
Can adjust the colour and brightness and can change the effects easily.
I like to take shots of my favorite part in movies and VLC helps me to do that.
Dislikes-
The Media Library needs to be improved though not a big thing it would make this player better.
Overall a cool player and my first choice to enjoy any video and I use this player even in my smartphone!
