I don't know that hull, but shallower V generally means a bit more speed and load carrying capacity for the same horsepower, at the expense of a harder or less comfortable ride when it chops up a bit. There's no single "correct" hull design - it's all just a question of what works for you.
If I wanted a rescue boat, I'd go deeper v. If I want a pleasure boat, I'd go shallower V. Driving style make a huge difference too (shallower V means you have more chance to clip across the top of the top, out performing the deeper V hull until it gets rough enough you can't "keep it up" safely any more).
In a pleasure boat, by the time it's that rough, I probably don't want to be out in it any way and will have headed home. In a rescue boat, you want to be able to keep plugging away regardless.
Made in Ukraine? The names "Golden Line" and "Grand Rib" sounds very chinese.....?
