It is generally accepted this crossing is good for the spokes.
Radial patterns can make a wheel stiffer laterally, but present other problems at the same time.
Although this is commonly done, I really can't see interlacing adding strength to a wheel, no more than tying and soldering would. It can help flatten a wheel, which is useful for derailleur cage clearance on the drive side of rear wheels. It is generally accepted this crossing is good for the spokes.
