Steem can ultimately total 666 million coins. SBD is fixed total of 3.5 million. Is SBD then better for rise in value?

Sorry to keep asking this question, but I'm new to the SteemIt family and I cannot find a clear answer to this question.
I read on another post that Steem can ultimately have 666 million coins by 2036. Steem will reach that number because of a built-in inflation of creating more Steem continuously. Yet SBD is a fixed total number of 3.5 million coins. So does that make SBD the better coin to trade/invest? Thanks in advance for any replies.
