Yep, quite often you get people slagging off the "!!!!e" climb performance and useless autopilot when it's pitching up or down to achieve the speed target. It just shows a lack of understanding.
I use VS quite often and something I like to do is display a page on the FMS which has climb N1 on it. As long as you're at that N1 with speed stable or increasing or below the N1 then it shouldn't be a problem. Still got to mind the shop though.
