Which is brighter (LED content)?

[insomniac2295]

So, I'm in the middle of implementing a light plate for one of my enclosures and I'm using 3 violet LEDs from Pedal Parts Plus. I'm using an LED calculator online to try to figure out how I can make them as bright as possible. It gave me two results for my LED array. Which one of these would be brighter? Do the different arrangements even make a difference?
I used 3.3 as the forward voltage.
