They pay top-of-band on an annual re-evaluation basis and offer an all cash <-> all equity choice. So pairing that down to the low end new grad scale at Big N ($150, $180k?), but getting that TC in all cash vs. the $120k base, $30k vested equity combos out there, is really life changing.
I don't think the cash vs stock thing changes the calculus much. You could just sell what stock you get anyway (I have mine at Google set to autosell at vest).
