I enjoyed Tale Spin much! I would probably make it equal with Rescue Rangers, but it might get bumped a little higher because wildcat sounded like Emo Philips.
There were things about both shows I disliked... for example if either show's episode of the day featured a character I didn;t like, I wouldn't want to watch it, because with those crappy characters came crappy scenarios.
The other shows (GB, DT, DWD) never had crappy characters or crappy scenarios. I feel bad also putting DWD just one notch above RR and TS, because it is a way way awesome show. But I mean, GB and DT were just intensely flawless.
Re: Gummi Bears, it was always so thrilling when they met new Gummis, like Gusto above, but not him so much as the gummis of Gummadoon, Ursalia, or New Gumbria i.e. if they used the Gummi Scope (is that the right name?) in an episode, you knew it was going to be an amazing one.
