I always thought the rule was go for all bombs on UFO's extra. Anyway, UFO's the last thing I want to do right now (GFW I don't plan to do at all =p). The stage is alright, Kogasa's doable aside from her last card (I can't react to lasers fast enough), but I'm god-awful at Nue, and I clipdeath and restart all the way there... At least SA has an easy stage (less restarts, more Koishi), and SoEW gives you craptons of lives >_>.
