I have a Kraken as well on my 230.6. I haven’t had others, so can’t compare. What I like about the design is that it’s in three sections with a narrow section in the middle. Don’t have to take The while top off to feed or do something on the left or right of the tank. Also, the back section of acrylic is pretty wide allowing for modification if you change light arms or something.
They have a template and the only thing I added was feed ports on each front corner with a feed cup. I cut the holes for the lights myself as I didn’t know exactly where I wanted them when ordered. Here’s a pic.
