Halo reach vs mw2? What do you think?

In my opinion i think halo reach, ive played mw2 but got too bored after a couple of weeks. besides there is going to be a lot of content in halo reach like firefight, theater, forge, campaign, and multiplayer. so what do is your opinion on which will be better??? p.s. have you seen their newest trailer "deliver hope" its awesome i swear they need to make a halo movie!
