I've used both quite a bit for various things.

The biggest differentiator is that Pixelblaze is built around the user being able to define their own patterns, while WLED is more built around getting a turn-key setup as easily as possible. One of the downsides to the Pixelblaze, for me, has been in instances where I just want a simple thing like a specific color, or a simple fade or pattern. While you can do that on the Pixelblaze it can take more time to tweak the PB code vs. just moving a couple of sliders in the WLED interface.
