spr332 vs spr532

[Elizabeth Ferdman]

Hello, 
I'm interning for the PGP Clean Room and am trying to get an OpenPGP
Card reader. Kernelconcepts is offering a SPR332 which is the successor
to the 532. According to this page, though,

https://wiki.gnupg.org/CardReader/PinpadInput

the 532 seems to be recommended but the 332 is not. I'm wondering if
there's a specific reason why it was left out and if I should go for the
532 instead.

Thank you,
Elizabeth
