I'm looking at you from across the room with my smug French Canadian face.
Jokes aside, I think Fragi is an amazing Rein one of the best in EU, if not all of the west. I also believe that while Shaz and Bigoose aren't as known as Grey and Neptuno they've been performing at a high enough level to enable their tanks and DPS to thrive.
As for the man to man match ups it was as you said, too close to really be a huge factor but I do still think that Gigantti had the advantage in overall skill, on top of better team play. I also want to highlight Linkzr. I feel like he doesn't get enough credit from you for the amount of clutch moments he's able to turn around. He's a driving force in a lot of the wins the were able to get imo.
In my opinion only the first map was realistically close here with C9 not being able to complete any of the other maps so I can't say it was super tight but still a very entertaining match overall.
Edit: added clarification, cause English is hard ok.
