I haven’t made the transition, but I do have the entire CC suite on my system. If you need any three applications in your workflow, the it makes sense to have the entire suite anyway. Most dedicated videos editors will most likely have Photoshop and After Effects needs anyway, so one more makes the monthly subscription for the entire suite a better deal. I have found myself using Illustrator, the full version of Adobe Acrobat (for notes and form making), and the other tools more often than I thought I would.
That being said, I have also kept an eye on Premiere as there is a lot to like about it and each release adds a lot of nice functionality all around. I have done short pieces with it, but as I work mainly in features, I have not made the transition as a lot of workflow day to day stuff is still easier to manage in Media Composer. But it is getting closer – the performance and size/quality of the monitors are very appealing to me for starters. They have almost all of MC’s trim, just a difference on how and when they are accessed which is the muscle memory part.
My two cents.
