Gyre: all red or purple shards, or a mix of both?

Hey so Ive been trying to figure out which is better on Gyre, important to note that I have no subsumes on or anything of the sort just regular Gyre prime. I would test it myself but I dont want to spend all those resources slotting and unslotting shards, so if anyone has the answer already I would be thankful. My goal for the build is being able to kill with her abilities and not just having her be a weapon buffer.
