Which Holy to ascend?

I’m looking for some advice. I currently have Joon, Justice and Vivica at full ascension. Kunchen is my only other 5* healer, he is maxed as well.

I also have Vivica, Joon, Justice and Leonidas at 1/1, and enough holy mats to fully ascend one of them.

Which would you pick, and why!

Thanks in advance!

I would work on Leonidas for variety. If he just isn’t what you want I would pick Joon as a close second. Two Joons on a purple titan would be pretty awesome.
