Picard has the built-in sweetener and ease of having a massively popular existing main character returning, being played by the same legendary actor who played him originally. It also avoids the incredible difficulties Discovery faced right out of the gate trying to be a TOS prequel, in effect irritating any TOS fans who don't want any change and simultaneously irritating the TNG era fans who wanted something post-Nemesis because (insert stupid rationale about how Star Trek must go forward).
I think the difference is, for me, that the Picard story feels like a natural outgrowth of the TNG mythos. Discovery never felt like an outgrowth of anything from TOS. It felt like it was bolted onto TOS in an attempt to drive subscriptions. And, yes, I understand that is exactly what Picard is here to do, just it feels like a far more natural evolution of the franchise, at this point.
With Picard, you also avoid the wrath of all the indignant white males who feel as though their identities are threatened by the very existence of a character like Michael Burnham, and you certainly don't need to deal with that baggage and agenda-driven bias with Picard
You're spot on here.
