I'm not really qualified to speak as to its statistical properties, but I've used this generator a couple times.

The biggest downside I ran into is that it requires 64 bit numbers even for the 32 bit RNG, which means its very simple code becomes more complex on a platform with only 32 bit numbers, or in a scripting language. Also, it's not a CSPRNG, if this matters to you.

This is minor though, and I would use it again. It's flexibility for seeding and easy serialization outweigh this IMO (and it's still simple compared to e.g. mtrand)
