I'm in the camp of Andor being top tier Star Wars media. It's hard to compare it to the original trilogy for various reasons, but it's the best filmed media they've made since. Of course, we need to see season 2, but season 1 on it's own is pretty awesome.
It may depend on what you want most out of SW...if your main interest is stuff related to The Force and Jedi, then this would probably be the most boring Star Wars ever. But personally my favorite stuff is everything to do with the underworld and the politics of the Empire. I am over the moon with the ISB stuff.
