The story behind my preference is based on the SPX end of week forecasting competition that used to be here at T2W. I found Woodie's to be a closer approximation than the others. However, for the daily or weekly time frames, I don't think it matters much between the Classic and Woodies.
For me, it's a quick and useful way to check re-affirm, S/R levels before setting Entry/Exit points.
And yes, I agree when they align with Fib levels they do become more significant targets which are usually hit sooner or later.
