There are a lot of WordPress.org plugins out there for embedding YouTube video. I evaluated few of them, the one I found to be the best is Better YouTube Embeds.
This plugin automatically detects the capability of your browser and decides whether to use Flash or HTML5. This enables the video to run on mobile devices where Flash is not available. The plugin also presents the latest video player with options like viewing video in full screen.
IFRAME Embed For YouTube functions in the same way as Better YouTube Embeds with one downside. It puts a link to developer site below the video.
Other plugins like YouTube Embed and Youtuber are also very simple to use but they implement an older way of embedding video, that’s why, they present an older version of video player where options like viewing in full screen are missing.
