Off the top of my head, and someone please correct any changed information...
Business card has lower AF, doesn't report on personal credit report , has a huge bonus for redeeming MRs for airfare, 50% points bonus on purchases of $5000 or more,
Personal has Uber credit, generally lower spending mark to get the signup bonus (often tiered, like 50k for this then another 25k or 50k for more on business), and you can add up to 3 additional Platinum Cards for authorized users getting all of the benefits (except Uber which is supposedly for the primary cardholder but some reports that it shares like the travel credit among all cards) for only $175 a year, whereas the business version is $300 per AU - both allow up to 99 Gold cards also, free for personal and last I checked $45 for business.

No problem. For a single card, the Biz card does seem to make much more sense. The business charge cards also tend to have other bonuses quite often that aren't available for personal cards, so with the difference in annual fees even if you did use Uber a lot it's easily a wash. Every time I type "up to 99 Gold cards" when discussing the personal Platinum, I still find myself scratching my head trying to figure out why they allow that many authorized users on a personal charge card.
