I don't really dig either extreme.
I like Numenara, but I ignore all pretense of "magic". IMO, Numenara isn't a fantasy setting. It's a really good "weird sci-fi" setting.
I dont know know Mage Ascencion, at all. Can't comment.
My preference for sci-fantasy is for a mix of elements. I kinda don't like settings or shows or whatever where there is basically just one type of thing. Everything supernatural is a "Fay", all magic is just advanced tech, etc.
I'm building a sci-fantasy world RN wherein physical magic, like pyromancy, is "completely" scientific, within the conceits of the setting. Ie, the universe left the formless infinite mass of hot density because a conscious Will existed, and all matter and physical reactions and states are effected, to some degree, conscious will (which is why observation changes stuff on a quantum states/processes). There is a whole thing with Thaumatological Particles which are Force Carrier Particles related to the Thaumatological Field, which completes the Grand Unified Theory. It's a whole thing that is more awesome than it sounds in the short post I'm willing to do on it right now.
So, if you wanna burn stuff, you must, as Harry Dresden puts it, do business with physics.
Summoning and binding magic is fairly similar, with some aspects being exceptions.
Gods, however, as well as Faith magic, shamanism, and a lot of the magic inherent to creatures, is fundamentally illogical.
Doesnt need to be one or the other.
