Any of those two will greatly help your employability. But if your goal is to start your own startup, and you're moving away from .NET only because > The cool startups don't use MS stack Then I recommend you strongly reconsider. Starting a startup is not about your coolness factor, but about the product you ship. Your users could not care less about what your technology stack is. If you take 6 months to master a technology you don't know, that's a lot of time where your are not actually developping your product.
