67 Barracuda lower quarter patch. Goodmark or Sherman?

After I removed the trunk extension on my Barracuda, I noticed a softball sized crunched in dent on the lower quarter panel with body filler spaghetti coming through it.

Ordered an AMD patch panel from another site and it's been on back order all summer. Called AMD and it looks like it's not even going to be made until sometime next year.

So now I'm down to either Goodmark or Sherman. Both are relatively the same price on Rockauto so I was just wondering which one you guys think I will have to do less work to? I'm not doing a full quarter, just a lower patch to get the dent and body filler out of there.
