Pick the Rokinon AF 14mm f/2.8 if you need an ultra-wide prime for landscapes, architecture, or astrophotography at a slightly lower price. Choose the Tamron SP 85mm f/1.8 if portrait work, low-light performance, or built-in stabilization (VC) is your priority, despite the higher weight and cost. The two lenses serve entirely different focal lengths, so your shooting needs will dictate the better choice.
