What reasons are there to get a Starrett instead of this one?

I have both this combination square and a Starrett. The Starrett is, of course, much more expensive; however, the Starrett is more accurate and better made. For woodworking, there are some things for which accuracy is very important. The Irwin square I have is out of square by about 1/128" over its length. If I use this to set the angle of my table saw or to make sure my miter gauge is true. 1/128" over 12 inches may not seem like much but it's enough to cause parts I cut to not fit, particularly cutting a wide board. The Starrett combination square is one of the few tools that I use every day in my shop. I expect the Starrett to last my lifetime. In fact, I have a Starrett protractor head and rule that I inherited. It's decades old, but it's completely serviceable and a pleasure to use.

Does this have metric markings as well?

one side is in units of 1/8th inch along one edge and 1/16th inch along the other edge on the ‘flip side’ it in units of 1/32nd inch along one edge and in metric i.e. centimetres (cm) & millimetres (mm) along the other edge it is a a good tool - well made and good value for the money
