Verdict

Spark 1.5% Cash Select

Spark Cash Select is the clean no-fee 1.5% Capital One option — plus a $750 bonus and 9 months of 0% on purchases. It is not Spark Cash Plus (NPSL, $150) and not Classic (fair credit, 1%). Best as a simple daily driver or year-1 0% tool; once annual spend is high enough that a 2% flat or category card wins, move the volume.

The Business Platinum Card® from American Express

Business Platinum is the lounge-and-credits SKU — not consumer Platinum (different credits, broader direct-airline 5X) and not Business Gold (lower fee, auto-4X ads/restaurants/gas). It pays when portal travel, 2X categories, and enrollment credits are real spend you already have. Unused credits make $895 a net loss versus Ink Preferred or a 2% cash card. Poor daily driver for flat cash back, 0% capital, no-PG underwriting, or flights ticketed direct with airlines.
