"Smoke" is probably the stronger of the two, but on both songs Truth Hurts is doing a very good job staying current without sounding like she's pandering to a marketplace that may or may not remember her.
It's nice to have her back though. With her, Michel'le, Latoiya Williams, El Debarge and others coming out in the next 6 months or so, real singing is really comin for those ears.
Bout damn time.
