So I'm about to move into a new office in the city, and am looking up ISPs. Looks like I'm lucky and able to get UFB.

I initially am looking at the residential plans:
http://www.telecom.co.nz/internet/plans/ultrafibre/?nid=mm446

Ultra Fibre 100 for 500gigs is $159/month. Not bad at all.

But then I happen to look at the business option:
http://www.telecom.co.nz/business/ourproducts/broadband/businessbroadband/

Not only do they have a far smaller range of choices than residential, but their top one is Ultra Fibre 100 with only 200gigs at a more expensive $167.29+GST per month!   Why???

And can I get the residential one instead?? (as I'll be living there after all)

Assuming I can go with residential, which should I pick:
