Japanese Shmups VS. US FPS

In Japan, danmaku are flooding entertainment. In America, even Wreck-It-Ralph is concerned about WWII FPS, Counterstrike, Call of Duty, Battlefield, etc., etc. Which genre do you prefer? I rather choose shmups, because of great soundtracks and simple gameplay. FPS make me feel "own3d" since the sniper character from Metroid Prime Hunters.

I like both, but I lean a little more towards FPS'es in terms of preferences, though both suffer from a similar sense of fatigue if you ask me. There are arguably more shmups out there than FPS'es, and just like the latter, they can feel pretty bland and uninspired. Radirgy, Mamoru-kun, and the latest Darius game have been some of my most played shmups in a long time. I'm not counting bullet hell style games in the mix since they're a bit more niche.
