Saying &amp;#8220;You&amp;#8217;re awesome&amp;#8221; means that what you have done is awe-inspiring and amazing.
Saying &amp;#8220;You&amp;#8217;re a nice person&amp;#8221; or &amp;#8220;I like you&amp;#8221; means that everything you are is nice and therefore, by extension, anything you do is also nice or something I like.
You decide which is better.
