Are third-party primes like Viltrox worth it versus first-party glass?

Specialist communities and independent reviewers are increasingly positive on Viltrox, with the AF 50mm f/1.4 Pro repeatedly described as punching well above its price for sharpness and bokeh. The main trade-offs reviewers note are slightly less refined autofocus than first-party flagships and a shorter track record, but for the money the consensus is strongly favorable.
