Both anime involving lots of high octane action scenes that primarily involve guns as the weapon of choice of the main characters. Cool characters and in general a whole lot of sweet gun toting action.
What ties these two together (other than the massive gun fights) is the animation style. Both were produced by Madhouse, and the animation is very similar. Characters are also fairly similar in attitude.
The Holy Grail War is a battle between seven magicians who each summon a mythical hero to fight for their cause. Shirou, a twice orphaned high school boy, had so little magical talent that his foster father did not bother teaching him about the war and its meaning.

The Grail grants the winner any wish they have. But driven by an unyielding sense of justice and self-sacrifice, for what will Shirou fight?
This recommendation may seem strange for some people as the story, art and such are all very different between Black Lagoon and FSN. This recommendation is for the person that likes strong female characters (more so in Black Lagoon) and some action mixed in. I just think if you liked one, you'd like the other.
Each of these series contain a strong female character that handles most of the violence that is present in each of them, and a main male character that is more or less pushed into an entirely new world that is marked with violence and death. Also, the main male attempts to act as somewhat of a moral conscience in each of the stories at some point.
What if roller skates had high power engines that enabled the skaters to do stunning new tricks that defy gravity? What if you saw a beautiful girl effortlessly glide through the air with them? To Ikki, this is reason enough to secretly borrow a pair of Air Treck skates, and step into an underground world filled with gang fights and strange customs. Enamored with high-flying stunts and the flirtatious Simca, Ikki forms an Air Treck gang of his own and starts a life of fighting rival gangs and flying over the rooftops, chasing the girl always one kick ahead of him.
Action scenes, though not dealing with similar content are liberally applied to both series'. Although Black Lagoon is not as flattering to the female figure as Air Gear is, there is a reasonable degree of eye candy in both. Not to mention the romantic element that both series share.

I'm not sure why I liked Bleach and Black Lagoon, but I did; call it instinct. The plots move along at a pretty good pace. Both male characters are torn from their everyday lives and are thrown into EXTRAORDINARY circumstances.
