I'm at Whiteman with 2 10" touchscreens and AFS Pilot autopilot in my 6. I love this panel. I'm pretty sure you'd be happy with any EFIS system, and I like that the AFS has a lot of buttons and knobs and very shallow menus. It's intuitive to use. Charts are relatively cheap at $100/year and you don't have to buy them if you don't need them. I use the map data which is free updates from AFS 95% or more of the time. The only downside to EFIS that I can see is that there is so much info that you have to make a point of prying your eyes away and look outside.
