If repop panels were the same gauge thickness as the original I might be tempted to go with the new panel if cost were not an issue. Replacement metal is really thin. I prefer to use patch panels in order to retain as much as the thick original as possible. In most cases I make my own patches. Even new replacement metal ends up covered with a little glass and filler when it is all done, so you may as well make your own. My .02.
