I try not to use either. In a lot of cases the issues that IE have can be avoided by simplifying the structure of your markup somewhat.

It also helps if you use a decent CSS reset like Eric Meyer's.

I am also slowly but surely dropping support for IE6 as a matter of principle, especially given the latest security issues with IE6 and IE7 - we're not going to change people's browsing habits and browser preferences if we keep supporting crappy browsers.
