The credits between the Capital One Venture X Rewards Credit Card and the Chase Sapphire Reserve are similar, but one is clearly easier to use than the other. Remember, you must use the Capital One Venture X credit through the Capital One Travel portal for flights, hotels, or rental cars. This isn't the case with the Chase Sapphire Reserve $300 travel credit. You can use it for just about anything travel-related, from airfare, hotels, rental cars, Airbnb, ferries, parking lots, buses, Uber, campgrounds, etc. And you don't have to book it through Chase's proprietary travel portal — simply use your card for a travel-related expense, and it'll be reimbursed. The one downside of the Chase Sapphire Reserve benefit is that you will not earn points for any purchases that get reimbursed by the credit.
