"The TPIC6C595 is the higher specification version of the TPIC6B595."

TPIC6C595 is rated for 100mA outputs, the TPIC6B595 for 150.
TPIC6A595 is rated for 350mA.

How is the 6C595 the higher spec version?

I think that was a typo.
The chip Sparkfun uses is a TPIC6C596.

I don't see a lot of differences in the data sheet from C595 & C596.

100mA drive each, while B595 is 150mA.

So I'd still like to why Paul___B thinks it is a higher spec version.

Sure, but even the lightest member of that family can do what OP needs (20mA/segment).
The TPIC6B595 seems to be common/cheap on ebay.
