I had both for a G19 and very much preferred the Mini. The Standard is huge, and the Mini offered plenty of support. There was no difference in comfort for me, but the Mini was easier to remove/install. The biggest thing to watch out for is the spacing of the belt clips working with the belt loops on the pants you wear. With that in mind, I bought both. I got lucky and they both worked with the pants I normally wear, so I quickly sold the Standard.
