I used to have the Titan's and really liked them but after owning two pairs that ripped by the thumb, I decided to upgrade to the Rovers.
Overall quality is the same and they are very warm, but oddly enough these gloves run MUCH smaller. To give you an idea I wore a large in the Titan and it was perfect. The XL Rover is still much smaller than the L Titan.
Regardless, I will always buy the Dakine gloves simply for the Google wiper. This thing works incredible well and while all my friends are complaining on the snowy days that they can't see out of their googles my little wipe comes to save the day.
Overall good product
