First Timer for FAS but not modeling. I went various plugins but mainly Positive Grid Amp/FX -> Yamaha THR -> Line 6 Helix LT/Native. It took me a solid month to "get" the FM3, in terms of learning the interface/Edit, how to edit/arrange things, etc.. I can now navigate around the FM3 pretty seamlessly. What I don't have a handle on yet are the THOUSANDS of available parameters on the dozens of blocks and hundreds of FX. But I'm not sure anyone but Cliff knows exactly how every editable parameter works! There is definitely a learning curve, for with great power comes great responsibility. When I say that it took me a month to "get it", I mean that it took that long to become comfortable with navigating, controlling, and creating with the FM3. By "get it" I mean not always having to pause to read the manuals or hit up Youtube or the forums. I was able to make it playable the first day as firing up very usable Factory presets was no problem. I would highly suggest purchasing AustinBuddy's Live Gold Pack as that's a tremendous intro to the FM3, primarily the amp models, and is very intuitive and easy to use.
