The ZWO LRGB 36mm imaging filter set has better transmission, better coating, and better color separation.
The band passes of the filters will combine to have weights approximately 1:1:1. The red filter cuts infra-red wavelengths, and there is a small gap between the green and red bands to minimize the effects of common sources of light pollution.
Narrow 2mm thickness filters allow minimal if any refocusing after switching filters.
