I really like Daiwas mag brake but PREFER shimanos VBS. There's really no comparing them because they work differently but when it comes to externally adjustable magnetic braking, Daiwa gets my pick, I really hate revo brakes, quantum has a highly effective braking system as well. Its really all about you're settings, I can set my curados and Chronarch noticeably looser than my daiwas but yield similar results.
You can set a shimano and never have to touch the brakes when changing baits but a daiwa may require a little tweak but that's why they make a cast control knob. As for which is better, i have 5 curados, a citica, and a Chronarch against 4 sols, an Alpha, a zillion, a pixy, and a fuego, Im kinda torn.
I think you'd really like the Alphas, never fished a TD-Z but I've heard great things
