Ace Combat 5 vs Ace Combat Zero

I was looking for AC5 to buy, but all they had was the Newer AC Zero, Has anyone played both and can tell me which is better? I Beat AC Zero in less then 5 hours of play on Easy Mode, and only did like 14 of the 55 Missions, It seemed kinda of fast and way way way to easy and too short for me. The Storyline was awesome, anyone have some suggestions? Is it worth finding AC5 and buying it or will it just be a waste of money like I think AC Zero was?

In my opinion, AC5 is actually a stronger game. While it is different than Zero, it has a storyline that actually plays out like a movie. You get to know the characters and when things happen you actually feel like you want to help them. (oops...maybe a little too much said....)

I'd say that it is worth getting. AC5 plays a lot like Zero, but the missions are a little more invigorating (like mission 27 *shudders*). It was one of the first two games I bought for my PS2 when I bought it back in May, and I would buy it again.
