Of the two, the first one is a far superior tree. The graft is better placed, the taper of the lower trunk is far better, it’s not leggy like the first one is, the color of the needles is better, the growth habit as evidenced by the tight tufts is better suited for bonsai.
I would buy the first, but I would not buy the second. Even if I didn’t have to choose between them, the second tree doesn’t have the qualities I look for when selecting JWP.
To give you an idea of a similiar tree I DID buy:
Decent lower trunk taper, foliage close to the trunk, good color, tight tufts. This one has two grafts: the lowest branch on the left is one, and the whole rest of the tree is a graft where the first branch on the right is. Unusual to have two JWP grafts on a single JBP trunk.
Keep in mind the selection criteria:
Trunk movement and taper;
Good quality foliage - color and tight tufts;
Condition - foliage close to the trunk (not leggy);
Good health.
