CoreXY printers absolutely do have more stable kinematics for better acceleration, but modern open printer firmware--mostly Klipper, though you can do it with Marlin in an unsatisfying way--implements resonance compensation, aka input shaping, in a way that really improves acceleration (which matters way more than top speed for most prints). My Sovol SV06 can make a really nice-quality 3DBenchy in 37 minutes after doing my input shaping samples. That's not as fast as an X1 Carbon, but it cost a quarter as much, and I tend to think that when it comes to 3D printers that bandwidth is more valuable than latency.
