Experienced Inventor user thinking of switching

I've been using inventor for 2-3 years and I was considering giving Creo a shot for a variety of reasons. What would you folks recommend I look out for in terms of differences between the two? Perhaps there are some youtube videos or blog posts I shout get to, or books I should read? I saw already

PTC Creo  -  Moving to Creo 2.0: Experiences from SolidWorks and Inventor Users

which was quite helpful.

Many thanks in advance
