Help me with my first r4

England73738

For context, I have explored all story content but I have done no endgame stuff whatsoever and plan to focus on Epoch next.

I have onslaught, photon, Kushala etc all unduped but think they do a fine job at r3 and I don’t really wanna do them unless anyone can persuade me otherwise. The 3 below are who I’m stuck between.

Edit: adding screenshot of top 7*s in case anyone wants to suggest anyone else
