White letters vs. Blackwall

Which do you guys prefer, raised white letters facing out or the blackwall facing out and why?

well, I think (at least for me) it depends on the type of car. My Euro with the chrome 5-stars looks good with blackwalls. But when (not if) I get my hands on a 70 chevelle or 75 Nova with some old school slotted rims, it's raised white letters all the way...
