I can't say anything about anything before the mid 90's since I wasn't...well...alive. So it really comes down to Fox Kids or Kids WB! Fox Kids gave me Goosebumps, Power Rangers, Digimon, and then later in the days of Fox Box they had good shows like TMNT, Sonic X, Kirby Right Back at Ya!, and on occasion I'd watch Ultimate Muscle, Shaman King, F-Zero. But Kids WB! took up most of my Saturday mornings with Pokemon, Yu-gi-Oh, Xiaolin Showdown, Ozzy & Drix, Static Shock, Batman Beyond, Sylvester & Tweety Mysteries, What's New Scooby-Doo?, Jackie Chan Adventures, and Megaman NT Warrior. All of these cartoons are far better than anything that CW4Kids has to offer nowadays IMO. But if I had to choose one, it would be Kids WB! Call it nostalgia, but I didn't really start watching Saturday morning cartoons until the late 90's when my friends got me into Pokemon (I'm gushing with nostalgia right now). I didn't really watch Saturday morning cartoons during Fox Kids peak.
