I wouldn't necessarily say "better for track days" - that depends on how your car is set up and your style. It's certainly more re-assuring and balanced, but it won't make you quicker into a corner.
If you've got a set up biased to oversteer, the last thing you want is more rear brakes. As you're steaming into a corner on the brakes, you want as much force on the front tyres as possible to get the nose in. The back will come light into O/S and you use this to ever so gently slide it around behind you. Loose is fast, but with it comes risk.
If your braking is 'flat', you're more likely to push the nose wide as the rear has too much grip (like having more rear camber than front). This is more for people who like to scrub off speed in a straight line, come off the brakes, then turn in. Your loose man above will have braked later and will still be braking on turn in... but you run less risk of getting it wrong.
There's no better option, just different set ups suit different styles.
