I guess for me the biggest difference compared to a Charybdis is that it’s a professional product.
I love the Charybdis as a project, but due to the price, I would rather go for something that can resist the test of time.
If you didn’t buy the Advantage 360 yet, there is a refurbished store and I found a $50 off coupon. Saved about $100 on the Advantage 360 Pro. The pro wound up being cheaper. You can use it for the backlight but wired if you don’t want Bluetooth.
