For larger projects, product changes, legislation updates, Khan Academy makes it easy to transfer information in an easy-to-digest manner. The software works really well with adult learning as it keeps users engaged in quick bite-sized lessons. It's more appropriate for larger changes and bigger implementations. It's less appropriate for smaller projects, or minor changes/updates, where quick training sessions would suffice.
I've only had to seek support one time. There was a glitch in one of my lessons and I submitted an email. The glitch was fixed by support within a few days, but I would've liked for it to be faster. However, I don't have a big complaint there because it is a free service.
The number one reason to choose Khan Academy over other options is price. If you are looking for a special skill or a quick answer YouTube is a great resource. Khan Academy is better suited for those who want to have a pseudo-classroom experience while still learning a subject or skill. I have used Lynda and Udemy; there is little difference between Khan Academy and those two options.
