Jiang Wei is known to be a very controversial character in the three kingdoms era. The guy draws from both sides of an argument, whether one praises him or one criticizes him.
The novel portrays Boyue as the last possible saviour of Shu giving all that he could to save the kingdom, only to be foiled by a weak internal government and a weak heart. He also has one of the most heroic deaths in the novel, truly giving his all until his last breath. He was the successor of Zhuge Liang and was one of the finest warriors of his time (he had the ability to catch an arrow in mid-air and shoot it back). In short, the novel portrayed him as the closest thing one could be to a perfect combination of wit and prowess.
Historically, he's a guy that had early successes in the northern campaigns but was defeated again by a weak internal government, but also by the combined abilities of the Wei army which included Deng Ai, Chen Tai, Zhong Hui and Guo Huai. He was simply outmatched by some of Wei's best. Boyue also had a massive defeat against Wei when reinforcements he thought he was going to receive never came and was blamed heavily for the loss.
In both cases, he tried to incite a rebellion which both failed. But in both cases, it caused the death of Deng Ai and Zhong Hui as well. As mentioned before, internal mismanagement limited his abilities somewhat as well.
So, where do you think he stands among Shu's generals?
