I use ctrl + prtscr to take a screenshot
then ctrl v to paste it into paint for editing.
nothing at all wrong with the old tried and true methods...
the snipping tool has a few neat things to it though..
1 - you can set a delay to when it snapshots the screen.. so if you need to open a menu and get mouse in place, where you cannot do this normally with the normal methods.. its great for that..
and 2 - it has an edit button within the tool that will open the screenshot directly in paint...
but thats the great thing, everyone has their methods, and theres plenty of options out there..
