Ink Preferred has a much higher signup bonus (but also a higher min spend). Here's a quick comparison:
INK PREFERRED
- 80,000 URs for $5k spend in 90 days
- $95 annual fee (NOT WAIVED)
- Earn 3 points per $1 on the first $150,000 spent in combined purchases on travel, shipping purchases, Internet, cable and phone services, and on advertising purchases made with social media sites and search engines each account anniversary year
- Earn 1 point per $1 on all other purchases
INK CASH
- 30,000 URs for $3k spend in 90 days
- NO annual fee
- Earn 5 points per $1 on the first $25,000 spent in combined purchases each account anniversary year at Office supply stores, Internet, Cable and Phone services
- Earn 2 points per $1 on the first $25,000 spent in combined purchases each account anniversary year at Gas Stations and Restaurants
- Earn 1 point per $1 on all other purchases
Due to the Signup bonus if the $5k isn't a problem, Ink Preferred is your better choice.
ALSO another point to consider is neither of these cards will report to your personal credit report (since they are Biz cards) SO while they are subject to the 5/24 application rule, they WILL NOT add to your 5/24 status.
EDIT: Also will add that CIP has "support links" on DISchurners. CIC does not offer "support links" but please don't let that factor affect your decision in any way. Do what's best for you

I only point that out so you weren't searching for CIC links, haha.
