First of all, your statement was that "Trump was the best president ever" and yet your reply talks about Obama. Obama did have problems from the very start because he never had the House and the Senate in his favor and his color also prevented many Whites from ever doing anything he suggested. As such, Obama's economy numbers were not great either. On top of that, he inherited a recession, which also prevented his numbers from being great.
But when you go back 50 years, neither Obama nor Trump can compare with other presidents. In fact, Democrat Clinton had triple the success with the economy than Trump did.
As such, your statement (and this reply of yours), means you are living in a fantasy world.
