Ok I like Marble and love this ship, but I realized something. I love it cause it's pretty much FlutterMac. Now I am sure there are those out there that will argue this. That she isn't but come on. She is extremely shy and quiet. Even here main is very similar with that one eye covered. It's FlutterMac with different colors and cutie mark.Now with that said. I do believe Mac would choose Marble over Fluttershy. As much as I have always loved the FlutterMac. I think he would choose her (if they turned out not to be related or if that even mattered). For the only real difference between Marble and Flutters. There work and family life. Marble is a farm girl. Don't get me wrong. Flutters is great with animals and nature, but when it comes to finding a mate that fits best with your life. Marble would be that. She would be a silent yet strong partner on the farm. Having lived that life. Also, she probably has a very strong connection to family. Which I feel Mac would also have.So in the end, MarbleMac is the better ship. Though I will never give up my FlutterMac.And this has been another rambling post.
