I'll give my 2 cents, and that's all it is! I have both. Purchased the sage in 2017 and the Black Hunter in February. Both bows I enjoy greatly. I also have a 30 inch draw length which is borderline problematic with both bows, and in particular the BH but to be clear it shoots fine for me. More finger pinch on the BH but very acceptable. The samick is more comfortable to shoot but I like and shoot the BH better (consistent & accurate). I have 35# and 40# limbs for the BH and both sets are about 2# underrated which is not a big deal. The samick is pretty close to its rated weight. Being able to switch limbs is nice but one doesn't want to do this every day. I did put a piece of felt in between the limbs and riser on the BH. The BH is, imo, crazy noisy out of the box but silencers do an incredible job! Regardless of the bow purchased, an improved string will help performance. Specs are easier to find for the samick, whereas the BH specs (particularly riser cut) are a bit more nebulous for the new owner.
Lastly, regarding the kits: I would be a bit leery of the kits as the items contained tend to be "throw ins" and better quality items could be purchased for not much more cost.
Hope this helps. Both bows are a very good way to get started!
