New Build, New Lights

[hhholds]

I am curious to any opinions out there about lighting choices. I am currently working on a 75gallon build (potentially upgrading to 108 gallon). I have 3 Radion Gen5 XR15 Pro lights for this build. Recently I acquired a brand new Orphek Atlantik iCon and OR3-90 Blue plus light bar (36"). I have ample enough light, I think, for a 48" tank. Would one set be better or possibly a combination of the brands?

The plan is mixed reef but trending heavy on the SPS when complete.

I thought about selling the Orpheks to help fund a bigger tank (the 108), which is dimensionally only wider at 47.24 in. x 23.62 in. x 22.44 in. vs the 75gal at 48x18x21
