You really should give the Clone Wars a chance. Rebels is a bit Saturday-morning-cartoony, but I think Clone Wars is probably better than the prequels, all things considered.
Plus I believe the same guy who is the showrunner for Mandalorian was the guy behind the Clone Wars, so there are going to be multiple “easter eggs” from that show popping up on the new one, I think.
One suggestion with Clone Wars -- look up "Clone Wars Chronological Order" and follow it for episodes. The first couple seasons were bad about jumping around in time, but if you watch them in timeline order they make a much better and cohesive story.
Also, don't get turned off by the Bratty Little Kid Ahsoka Tano early on, the character finally "grows up" as the series progresses.
