Better to use LMU's online application or the Common App?

I’m a transfer student looking into early decision for LMU. I actually applied and was accepted to LMU out of high school but chose a different school, and am now re-applying. The first time around I used the common app, but now I’ve checked out LMU’s site some more and it looks like they have their own. It’s kinda barebones though. Would it show more interest to use their application?

@QrtyUiop It doesn’t matter. I would say the more complete you make your application the better.
