Hi all, New user here, thanks in advance for your help. I currently use a Starwood Amex to book all my travel and also use it as my business expense credit card. I just achieved silver status on United (finally woo hoo!) and am curious about switching over to the mileageplus or sapphire card. What's recommended? Or do i just stick with SPG so i can keep getting SPG points? Really unsure of what to do here. Appreciate the help.
