This was not a good expansion.
Raids were not very fun (except the first one, which was ok), dungeons were not the best. Torghast, the new "roguelike" mode was turned into a grind to obtain currency for legendaries, which made the mode forced and boring, especially if you were playing alts.

And the story was...bad to say at least.

At least zones were good looking.

Without having played more than an hour of Dragonflight, as a player since beta of WoW I can confidently say Shadowlands was the absolute worst expansion pack and version of the game to date. Every single thing is gated. Overlapping, interwoven systems of gating/grinding that make the slightest bit of power gain an insane chore whether it was Korthia dailies, Zereth Mortis dailies, mythics, etc. On top of that, the dungeons and lore were mostly boring and ridiculous and Sylvanas was already irredeemable trash before WoW even started, but the story once again takes a poop on the only remaining decent characters in the franchise and the Jailer is a boring villain.
