Yep, this is my experience. From force of habit, I thought I could not function without seeing my list of open applications somewhere on the screen at all times. I decided to try the vanilla Gnome experience for a few weeks without any panel extensions like this to see what I was missing. I quickly found that switching apps via the hot-corner (or the three-finger swipe-up when using a trackpad) was intuitive and convenient. I also appreciated the extra screen real estate that comes from not having the app list displayed all the time...
