Star Wars has always been more fantasy than Science fiction. Something that is almost forgotten after the sequels were made and up until now with Ahsoka.
Ahsoka series feels like a direct continuation from the prequel and original movies. (Though, It could be an advantage to have seen at least Rebels to get the finer nuisances of the story telling. Maybe Also Clone wars series).
Though I liked Andor, Rogue one and even Obi-wan Kenobi series, they did not have the fantasy aesthetics as the originals Somehow more sterile and more towards science fiction(with primarily humans) than fantasy. They were missing mystery, occult-like scenarios, magic ...and they had a serious lack fantasy steeds, creatures and beings.
They barely touched the realm of Knights, Princesses, Evil rulers, Slaves and people/creatures with strange powers and sinister fortresses.
All this was remedied by the arrival of Ahsoka.
If you liked the original movies and the prequels, then it is a must to see Ahsoka.
