Are you allowed to like both!
I liked that Mando existed for a bit in his own personal somewhat inconsequential hero quest, not allot of effect on the big picture.
At once building up his personal armor, signet, weapons, (faceless) identity towards what he deems the idealized Mando, while simultaneously chipping away at that same, rules, armor. identity, the "way", towards finding his own.
Having completed his quest, he's left holding what we find is some great defining symbol of all Mandalorians.
So who he is, what he does with that next, is a great set-up for his next arc.
On the other hand, Fett is from the go taken to, and positioned into a completley different status quo and role, set to take over the criminal underworld.
Who likley doesn't give crap about the fate of Mandalor, only as much it will serve his interests.
Both these shows (and characters) have their own strong identity, and intrigue me, as well as where they might eventually cross back over, likley with the Jedi (Ahsoka) show, and whatever Rangers/Republic themed narrative they might still spin-off, all have to come together to defeat likley Thrawn.
