I like Tobirama but I fail to see what makes him more impressive then Kakashi or minato.
Kakashi has the reputation to be kage, he's well known and still powerful. Put him against the current kage or the previous gen and he should clear everyone with mid difficulty except Minato. Most of the akastuki can't compete with him either unless your talking about Nagato or Itachi.
Gaara is still a beast and would decimate some characters through sheer scale of his attacks. Seriously, he'd clown MS sasuke and Itachi.
Unfortunately, its because of him this war was allowed to begin, thanks to the Edo Tensei. He also created the Hiraishin technique, which is now the 4ths signature.
