Its hard to tell from pics, especially since it looks like the mousy steer is standing on rocks...but I personally like the paint better from these pics...they both look to be fairly powerful steers throughout...but looking at their feet I think the paint appears to have more natural base width...if they are both weighing the same I would say the mousy steer appears to be a more moderate framed steer, but at the same time I think the paint looks more correct on his hind legs, mouse steer looks a little straight and up on his toes(but this could be the rocks) I also like the levelness down the paints top...I will say that the mouse looks to be a softer made, easier conditioning steer, but just from the pics and not being able to handle him I would almost worry about him being just a tick over finished.
BUT this is just comparing them to each other...they are both very nice steers and I think you can be proud of the job you did with them
