Between gao and fu style bagua what are the points that separate the styles and which is better in combat?

I study Yin style(Lion system) which I think is one of the most direct and powerful of the Ba-Gua systems that I have seen. The Fu style is part of the Yin or YinFu style. In my opinion the Yin or Fu style is a little more direct and not quite as "flashy" as the Gao style, now every Ba-Gua system that I have seen is BEAUTIFUL and EFFECTIVE if the basic PRINCIPLES of Ba-Gua are followed. Type in Gao and Yin style Ba-Gua in Wikipedia for more info, I hope this helps!
