On perks and redemptions, only the Atmos Rewards Summit gets you into airport lounges. Weigh those against the fee, since credits and lounge access only count if you will actually use them.
Transfer partners and point value
Neither card earns transferable points, so redemptions are cash-back or fixed portal value on both, roughly a cent per point. There is no airline or hotel transfer angle to separate them.
Both are mid-premium airline cards with a companion benefit, so it comes down to Alaska versus Delta.
The Summit’s Global Companion Award and 3x dining reward Alaska loyalists. The Delta Platinum’s companion certificate can be worth more than its fee for a domestic Delta flyer, plus free bags. Alaska vs Delta, each with a companion perk.
