Is Fallout New Vegas less glitchy on the Xbox 360?

I have played both fallout 3 and fallout New Vegas on Xbox360. I JUST got Fallout New Vegas only a few days ago, but so far, it lives up to it's reviews. Game-play is pretty good I have encounter several glitches so far though including; game freezing, missing items, glitch streets and walkways and lost data. Compared to Fallout 3, their are more gun options and Hardcore Mode offers a much more challenging game-play. their are a lot of different perks, and perks that you can earlier on on in Fallout 3 compared to New Vegas. Overall, personally, i give fallout 3 a 8.6 and New Vegas gets a 8.0 because i think the quests are more fun on 3 compared to New Vegas. but that's just me.
