Flash vs. Toon Boom

So I was just about to get started mapping out the storyboard and animatic for the first episode of Punch Card Zombies, but first I did my daily reading of blogs and tweets that I follow in the animation/digital design realm. I started to notice a lot of blogs about how Flash is going to be phased out in the future, HTML5 is the new wave, .FLA files are going to be extinct, Toon Boom is better for animation, etc. Seemed a little disheartening since I pretty much make a living off of Adobe Flash.

Thankfully, my company is a little behind on software upgrades and our clients still demand Flash player 8 and actionScript 2.0 so we don't have a need to supply the latest and greatest technology out there. However, for my personal animation projects I was considering switching to Toon Boom to see just how much better it actually is for traditional 2D digital animation. It seems like it'd be like taking a few steps back at first since I would have to learn a whole new interface and software system, but maybe once I grew accustomed to the new layout it'd streamline the process. Does anyone have experience with Flash vs. Toon Boom and is one better than the other for certain projects?
