Opinion needed between Steiner, NF, and Leupold

Hi all,

I’m looking for a scope to put on a bolt gun strictly for precise target shooting out to 200 yd. My eyes are not the greatest so need about 18-20x to see the target for precise hits.

I will not be doing matches so weight is not a huge consideration but would be nice if not a brick. Highest priority is optical clarity, eye box, and FOV.

Unfortunately I don’t have anything locally to look at so looking for opinions between NX8 2.5-20, leupold mark 5 hd 3.5-18, Steiner T6x, and perhaps vortex gen3 4-24.

Appreciate the assist.

TIA
