Chargers are already described by Levels: Level 1 is wall-outlet 120, Level 2 is "dryer outlet" 240, Level 3+ is "super-charger"/CHaDeMO. Most car displays show estimated charging times for each level in one way or another.
"Refuel experience" is a red herring at best. Partly because the ubiquity of the electric grid means that you can charge anywhere: that's the subtle game changer that doesn't always come across when someone new to electric vehicles thinks about them. A Level 1 trickle charge while I'm asleep at home is plenty for my daily work commute. My car is parked nearly the same amount of time in my work parking lot: if the office park added a Level 1 or Level 2 charger next to the street lamp I park by I'd almost never need to charge at home.
Road trips are definitely the exception to the daily grind, and are the place where you really want a good "refuel experience". I think Tesla's superchargers fit that fine, but obviously there's a range currently to people's road trip experience. (90% of 300+ miles in 30 minutes; that's about my bladder range and 30 minutes is a light snack, a good stretch, and a brief glance at Twitter or a chapter of a good book.) It might get better than that as battery tech changes, but let's face it that we're at a good enough start now that we should stop dismissing electric cars because you don't think they have a "refuel experience".
