if your panels are repairable,then i'd patch them.
in my experience,even the "good ones" like Goodmark can have some pretty serious fittment issues.
i did full quarters on a 442,and a 68 Camaro recently,and they were 1/4"-3/16" different from the stock panels (both directions). this creats A LOT of extra work when making gaps and lines match up,and just getting it to fit and look decent.
I'm not trying to talk down about Goodmark or any other aftermarket suppliers. they are great,and they do their best. But nothing compares to stock sheetmetal.
