The pricey alternative is if you want the absolute best. The free alternative is already (with high probability, based on Erjang and more recent improvements) much better than BEAM. Not to mention the costs you save by not writing C code and having an immense selection of high-quality libraries to choose from.

Do you have proof that Erjang is better than Erland/BEAM with real-world benchmarks? Far as libraries, I'd agree with you that there's more. The quality part varies per library.
