The higher mounts are a trade off between the more upright head position for standing and a less solid cheek weld when using a magnified optic with a smaller eye box. This can be overcome by using a stock with a higher cheek piece, but that isn't always an option on an AR because of the charging handle location. If you look at the stock that Daniel Horner uses, you can see how much higher the cheek piece is to compensate for the 1.93 mount.
