Zhao Yun was never a major commander in Shu's camp. My view is that he was same as Maeda in Oda's camp in Sengoku. He had been following Liu Bei for a long time but we never see any thing major from him. Even Huang Zhong defeated Xia Hou Yuan, but Zhao Yun had nothing.
About Zhao Yun having brain, ie being good in tactic and strategy, SGZ shows nothing about it. Beside he was never in the same rank as Guan, Zhang, Huang and Ma. The highest title he held was 镇东将军, (Commander/General of the Eastern Defence), while Huang Zhong was Hou Jiang Jun 后将军 (rear general). There is a big gap between the two.
Zhang Fei was a better tactican than Zhao Yun as shown by the existing historical evidence, as he managed to surprise Zhang He in a mountain in Han Zhong.
