The size of the wrist opening and finger stalls should be very similar between the two models. The Shoeless Joe model should come more broken-in the the Rawlings Gamer Youth upon arrival. In terms of quality, I personally prefer the Rawlings Gamer series, but both are good youth options.
The 2017 Rawlings Gamer Youth Pro Taper 11" Baseball Glove: GYPT1-1B will weigh roughly 17.7 ounces. As for the weight of the older model in comparison to other 11 inch youth gloves it would be tough to say what the "average" weight is.
The leather is the same quality and the performance is the same. Both require a little break in period. the difference is in the look of the gloves and the webbing. The GPL had a closed webbing while the 2017 Rawlings Gamer Youth Pro Taper 11" Baseball Glove (GYPT1-1B) is a single post web.
