TL;DR. Personal versus business Platinum at the same $895 fee. Personal Platinum has Saks, digital entertainment, Walmart+, CLEAR, and broad consumer credits. Business Platinum has Dell, Indeed, Adobe, and Walmart+ credits. The business version earns 1.5x on purchases over $5k (unique). Same Centurion Lounge access. Pick based on whether your spend is personal or business.
The three dimensions that actually decide it. First, credit category alignment. Personal credits (Saks, Walmart+, Equinox-equivalent) are consumer-facing. Business credits (Dell, Indeed, Adobe) are SMB-facing. Match to your actual spend. Second, 1.5x on $5k+ purchases. Business has this; personal does not. Useful for businesses that drop $5k+ on equipment or software annually. Third, welcome offer. Both currently 150-175k MR on $8k-$20k spend. Check both before applying.
Real customer scenario for each. If you run an agency and spend on Dell hardware, Indeed job postings, and Adobe Creative Cloud, Business Platinum's credits genuinely net out. If instead you are a consumer who shops at Saks and uses CLEAR, personal Platinum is the better fit.
The trap to avoid. Holding both. The Centurion Lounge access does not stack. You are paying $1,790 a year in combined fees for one set of perks. Pick one tier.
