Go with something you've never tried before. Not only for the intellectual challenge, but because it will pay off in the long run: make you more versatile, better understanding of different programming paradigms, open new doors to positions at companies that aren't .net/PHP shops. Python with Django and Angular is a solid option, particularly with the widespread adoption of the language. Ruby on Rails is a popular choice too, but less use in the traditional corporate world (which I guess is your space, given .net). Some may say functional programming, but less commercial value. Go is a great language too, but haven't played with any mvc framework yet.
