Just depends on your Fuse really. Most of the heavy Fuses actually turn easier than the lighter weight ones. The Fuse is a little finicky in regards to power, but it can be made to turn in all kinds of ways (burner, Stingray no-return right angle, Leopard-ish), can go extremely straight with minimal fade at the end, and will even hold a decent hyzer if the wind isn't too bad. You'll probably grow to love it, but there's not a whole lot of overlap with the Axis, imo.
As much as I love my Cores and could pick them as a one-only disc, I think the Fuse paired with a stable mid like the Pain or Vector is an ideal combo for most conditions. That leaves the neutral discs like Core, Axis, QMS, etc. in the don't-need-it-unless-you-love-it slot. That's the biggest reason my Axes aren't really getting much use now except in field practice.
