I wouldn't normally consider these two to be polar opposites, except maybe on the budget. FDR tried to bring the budget back into balance once he thought the economy was back on track, but that lead to the recession of 1937-8. Conversely, Reagan didn't worry about trying to balance the budget, which in part is why the economy did so well.
I would hardly say that unemployment never going under 7 percent during his whole term in office is an economy that is doing "well," especially when you compare it to the almost nonexistent unemployment figures of the 1950s and 1960s, or the near total employment of everyone in the country during Roosevelt's Third Term. As far as neoliberal Presidencies go, Reagan definitely did the worst job of handling unemployment, although Obama definitely gives him a run for his money there, with Clinton doing the best thanks to the tech boom of the 1990s.
Well, if we want the success Roosevelt had with unemployment in his third term, I guess we can always just have another world war.
