Brian Taylor does make good plans. I have not looked over his plans enough to render a qualified opinion.
I have had a look at Don's plans and can say that they are excellent. He is making component parts such as resin exhaust stacks and other touches to really flesh out the design. Although I will say that the lines are good, but Don does leave a lot up to the modeler in terms of small details (panel lines, cockpit etc.)
