Well for me it doesn't. I've always been a 2 striker kind of guy but after the rave reviews about 4231 I'd be lying if it hadn't turned my head. Tried holding off but thought I'd try it for a few games and was disappointed, thought it offered no creativity.
Been using 41212 or 442 since I've been playing fifa (since 1997) and I just prefer the two at top. So if it works for you fair play I wont judge i just reckon it's overrated!
