The Sporty videos take more time to go in depth as to why things do what
they do. Unlike other video series that just give you information for the
exam. There are also more video footage of the subjects unlike other series
that strictly teach. Both are good, it just depends on much you want to be
entertained.
IMHO the main premise of the other videos out there is to get you to
pass the written test ASAP so that you can focus on passing your practical
test.
