The 145's Honeywell is definitely more user-friendly than the Universal, and I love the scratchpad. It's much easier to find what you want in the Honeywell, and the Universal's "fuel required/remaining" computations will scare anybody who's not used to it (they go solely off current fuel flow, so when climbing out they're always in the red). However, once you get used to the Universal, it's a much better box. The problem is remembering how to do what you want.
As far as the 145's climb schedule: 270/.56M is what you'll get if you climb out in FLC mode. I have done that exactly once, and it scared the heck out of me.
