The bend across the top of the first one makes it look like it will no bend as easy. The second one looks more "professionally" built.
Which is heavier? Which has the thickest center plate? That would be my choice.
I bought a Titan Universal to Skid Steer Adapter. You have to add your own loader brackets to the rear, front is Skid Steer. It was not flat across the skid steer mounts. I am guessing when they welded it together they warped it. I used my hydraulic press to straighten it. I had to kink the square tubing cross bar.
