Let's break this down:
1) In terms of their very very first clashes, Loki clearly performed the best between him and the wings, as the shockwave from his clash was much more significant and Imu powered (?) up, or at the very least made himself bigger to clash with Loki.
Though overall, the end result was the same except if anything, Loki ended up taking a much more visually fatal attack than Zoro and Sanji did. The difference being Imu didn't run away this time so the fight continued once Loki got up, whereas with the wings that was the end of the clash as Imu left. Although it looks like Sanji may actually be down as is that him being carried by Bonney? I can't tell. The wings were neg-diff and Loki is low-diff.
2) Mihawk and Imu are undeniably related, and a black blade just floored your god-tier Loki (😭). Mihawk/black blade stocks are going to the MOON.
3) Gah DAMN Imu is genuinely ridiculous as this man Loki is getting straight mollywhopped, but at the same time Loki's endurance is actually insane - for once, Oda is doing a good job at highlighting Imu's strength without diminishing Loki's.
4) One Piece is officially Naruto, this is so ass 😭
