For a hunting rifle, I presume?
Of your choices, the Swarovski, the Vortex would be last. For 1 thing, it's FFP and I prefer SFP for hunting. (If I hunted out west, I may feel different.) ANother thing, I think the other all have better glass, clarity and light transmission. There are several other good choices out there though. Leica, Zeiss, S&B, all have models within your budget.
There are several other factors to consider, range, terrain, species, caliber, rifle type, etc... For a whole bunch of reasons, when I'm looking for a hunting scope, I start with Swarovski.
And just to finish my thoughts, the SHV and VX-5 would be about a toss up for me.
