The VX5HD is going to be the most forgiving in regards to eye box and eye relief.
Not a fan of the NX8, the eye box is terrible and when hunting that's the last thing I want to worry about.
Can't go wrong with the NXS though, I didn't enjoy the glass much and the dials on the SHV but that's apparent when you look at the price range.
The PSTII is a target scope at the end of the day.
VX5HD 3-15x44 would be my pick given your price is probably more around $1,200 .. don't forget about the Zeiss V4 4-16x44 as well.
