Tower of Light done, what next?

Do you all recommend lapping the tower of light or doing the other two towers for the first time? The wiki is only showing the rewards for the first 3 levels of the tower of light on lap 2.

If you're competing for a high ranking, you should probably stick with the tower of light and crimson, but I personally like to finish each tower at least once in order to get the event units at the end of the first lap.

As far so I can tell, the rewards on the second lap are random. I personally got for lap 2 of light 1.5k Brave, a bunch of luna, and a 10 soul stones (s). Either way the rewards at the top of lap two would theoretically be better than the other two towers. And definitely do the Crimson when you get the chace (for free). There is another tower opening on the 23rd. Not sure what the rewards are or how many gems it takes, but its there XD
