Personally, I think the H59 is the best reticle Horus has done so far. Just about everything that's come before it has plenty of things I didn't like, most of which is just how busy they can get at mid-to-max magnification. The H59 is a nice balance, but some people just have an aversion to them the same way some people have aversions to bullpups - there's no rhyme or reason, just personal preference. I think they're most effectively employed on short action semi-autos because you can spot the splash, move the POI to the new POA and pretty much hit every time inside the effective range of the rifle. That's been my experience with an H59 on my Mk12 clone. That said, for a bolt gun I can see it being handy if you want to make accurate holdovers, say for rapid engagements between varying distances.
But if you've never shot one you would be wise to get behind one and see if it'll excite you or turn you off. If you spend the majority of your time at min or max magnification, then it's probably best to stay away because that's when the reticle seems the most problematic, IMO.
