All things being equal, wanboot should be significantly faster than standard tftp-based boots since you aren't stuck with a lock-step protocol. That said, there are obviously bugs in some platforms that need resolution. File bugs, as always. The installed base issue is a rapidly declining problem, because essentially all of the non-wanboot-capable platforms will be out of service life by the end of 2010, a very few outliers go into the first half of 2011.
