How user friendly is Presonus Studio 3 Professional?

I am new to PreSonus and I am excited to dive into the software. I have been using Sonar Platinum for the last two years and was very used to that platform. Are there any Sonar Platinum users that have switched to PreSonus Professional and are there any "go to" video tutorials for me? I would like to approach this as I dont know anything about this recording software and be able to lea and utilize it to its full potential.

Thank you in advance.
