I had an early 2008 White MacBook and then got an Aluminum MacBook when I destroyed the White one (got it wet). I'm still using the Aluminum one. Performance was basically identical. The Al model has a better, buttonless trackpad and a backlit keyboard. The Al has a Minidisplayport instead of minidvi connector, which was a disadvantage for me as I had occasional use of composite video out which the minidisplayport cannot do.
The White Macbook looked pretty sad after a year, while the Aluminum one looks like new today, and I don't treat it any differently except for not trying to clean it!
I'd strongly suggest the Aluminum model over the White.

I also like the white unibody bit that was 2009/2010
the white uni is one of my favourite designs. The metal is annoying after a while. white was apples colour.I have the mid 2010 and love it. I'll definitely keep this for years to come. I might hand it off to my wife but, it's staying on the family.
I'd suggest the white and just take care of it.

In computers, newer is typically better.
However, you don't mention your budget, your requirements, or exactly what models you're considering.
Without knowing more details, I'd say go with the newest you can afford.
