The Mizuno Global Elite Jinama Leather Series: GGE50J1 has more of a clay red color hue to it.
All of the gloves mentioned contain the best leather the manufacture has to offer. With that being said, a major factor could be the webbing and weight. The A2000 has a superskin making it stay dry reduces weight. The durability depends on how often you use it and how well you take care of it. But they all have very similar break in periods making the stiffness comparable across all of them.
Both gloves will be very good performers. Personally I like the Heart of the Hide models a bit better, as the leather quality is slightly higher, and the one I own has served me well for several years.
