Considering our other options are:

Tsunade: Weaker healing than Hashi, when it's supposedly her greatest strength

Kakashi: Strength was never his strong suit. versatile, but not really much against the other Hokage

Hiruzen: complete unknown in his prime

I'd say your list is about right. I'd take off Minato's Bijuu mode though; he didn't have it as Hokage.
