That is a great video.
As far as what method is "better" on our scopes, either one will work just fine. Your choice would probably depend on if you had assistance, how large your scope was, and how familiar you are collimating telescopes.
If you set your scope 1/2 way through it's motions (45 degrees in ALT) and that means you need a ladder to look into the autocollimator, then using the fine adjustments on the secondary would be easier. That way you are making your adjustments while looking, rather than going back and forth and checking your work.
I have to admit that I cheat and first collimate with the Glatter BLUG, then double check with the Catseye. 95% of the time it is perfect and requires no further attention.
The best advice I can give is to practice on a rainy day. No rush before sunset, no one distracting you with questions about your scope, just relax and experiment. Get it collimated, then mess it up and do it again. 5-10 times and you will be a master.
While looking through the autocollimator, press (rather than turn) the 4 knobs on the secondary and watch how the center spots stack and unstack.
The main thing is to relax and practice. Once you have the hang of collimation, it will take you less than one minute to complete.
Anyone who comes out to our shops always gets a collimation run through. It is 100x easier when someone just shows you how to do it, rather than reading 20 pages of theory.
