Sportsmans Warehouse here in Puyallup had the HS LR 4-16 on sale for $399 recently.. so if you go with that one you might want to check with them.. it's a hulluva deal.
I picked one up on the sale, and it's an awesome piece of glass. I was going to pick up a different scope, but it was too good of a deal to pass up. My only complaint was the elevation turret is in 1/2 MOA increments.. kind of a bummer. The HS T would have been my choice if they had the 4-16 in a 50mm obj, and it was on that good of a sale.
EDIT: I just realized you were talking about the 6-24. In that case I would certainly go with the HS T. The HS LR is still 1/2 MOA adjustments on the 6-24, and the windage turret is capped which I'm not a huge fan of. Also, the scope is only available in first focal plane. If you want that, great.. but if not - you're paying a lot more for something you won't use. Either way - that 1/2 MOA elevation turret is a huge drawback for anything long range.
