Money matters: at 1000 units, the LP2032SM would have been USD 0.64
each at 1200 units (2 reels of 600 each), the 1060 is 0.95 @ 1000 as
cut tape and a surprising 1.21 @ 1000 on reels (500 each). The 1059 is
0.95 @ 1000 (no reels offered at Digi-Key).

The bigger part is cheaper than the simple one? Something seems to be wrong wit the sales guys :P

I don't have any experience with coin battery holders, but also like the 1060 the most, because it looks easier for repairing than the others.
