I own both reels and I have no complaints against either. Frankly, all things being equal, the Curado DC 150 probably casts a bit farther.
Curado DC 150: The digital system samples the reel angular velocity (think RPM) every 1/1000 of a second and adjusts the braking to prevent backlash (overrun). You need to set the tension knob so the reel shaft has no back and forth play. After that, set the magnetic brake adjustment to 2 - braid, 3- fluorocarbon, 4 - dock skipping, and 1 for bombing it a mile. It makes a faint humming sound when you cast it (charging DC system). It is an amazing reel by any measure!
Chronarch MGL: This reel has an adjustable external magnetic brake (clicking noise tells you your changing the settings), but it also has internal pins you can have 'on' or 'off'. I've only had the reel 1 month and I haven't even opened the reel to change the factory settings. I've fished with it 6 - 10 times and it does cast like a dream and there is no charging noise.
I'm not a profession fisherman and I haven't adjusted the Chonarch's internal magnetic pins, so someone experienced may feel the Chronarch is superior if adjusted properly.
If I had to choose one reel over the other I'd flip a coin - to me, they are that close in performance.
