I wish I had had some glider experience before transitioning to powered aircraft.
All power planes are adequate for gliding experience with the throttle(s) closed! That's the way I teach landings, 'works great! Once you master a good glide approach, you can use a little power if you need to!
Yesterday it was full forward slips down final and to the flare in the Cub for my charge, she did really well. I can't think of the last time we carried power down final at all.....
