Is the sony e 50mm f 1 8 oss worth it?
Yes, I think it's worth it, especially if you shoot people, food, or anything in low light. At f/1.8 it gathers plenty of light and gives a soft background. It also has stabilisation and autofocus, which many budget primes lack.
On an APS-C Sony E body like the a6000 or a6400, it frames like a classic 75mm portrait lens, which is a flattering focal length for faces. The portraits guide calls the 50mm f/1.8 the cheapest great lens in photography. If you're building a kit, the first lenses guide recommends a fast standard prime alongside a standard zoom.
It's a prime, so you'll zoom with your feet. If you want one lens for everything, a zoom is more practical.
