New light(s) for WB 55.2: AI blade or XR15 G6 for LPS dominant

[JTRReef]

I recently got an established (1 year old) water box 55.2 frag tank that had some coral and a few fish. There are 4 corals that were doing well, a yellow hammer 4” diameter, a zoa patch, a purple stylo and a monti. It came with an AI Sol 16 light that seems ok but some regions of the tank aren't well lit and I read it’s not great for coral growth. I have added another hammer, and will be adding a 3rd hammer, a couple favia and a cyphastrea. This is my first tank and will likely remain an LPS dominant tank, potentially some SPS down the road.
I was looking at the AI blades (1x grow 1x glow) or the XR 15 Pro G6 as an upgrade. Which one would you go with or are there some of other lights I ought to consider? Tank is 24x24x16 inches deep. Thanks!
