Refractors give more contrast and I think sharpness, but can give false colouring (chromatic abberation). There are limits with reflectors (obstructed by secondary mirror) with low power widefield views. Coma more prevalent in reflectors I believe (affects edges of view, mainly in 'fast' scopes). Also depends a lot on your focal length, f/ratio and eyepieces, not just basic reflector vs refractor design. Can't speak for astrophotography.
