Which should I recommend, 10.04 vs 11.04?

I've been running 10.04 for a while now. I use it for development purposes and recreation, and I love it. My friend recently had to reformat his computer because he got a virus. Naturally, he is looking to try out Ubuntu (instead of his Windows 7).My friend would only use this for recreation/writing papers/etc., and he is not that tech savy.

I am torn because I know 10.04 would be more stable for him, but the 11.04 desktop looks interesting.

From your experience, are new features in 11.04 worth the instability? For you users of 11.04, how stable is it? Does it have noticeable problems?

I know it's a matter of preference, so I'm searching for opinions.

Should I recommend 10.04 or 11.04?

Thanks for your responses!
