The Chase Sapphire Reserve allows you to earn 3 Ultimate Rewards points per $1 spent on travel and dining, and you can transfer 1-for-1 to MileagePlus if you so wish. I would then combine it with the Chase Freedom Unlimited, which gets you 1.5 UR points per $1 spent on everything else. I would value that over spend on the MileagePlus Club Card, as you are not solely restricted to United's redemption availability (since Ultimate Rewards has other transfer partners).
