In terms of elegibility for Husbandom, the Fourth Grail War Masters rank like this: Tokiomi > Kayneth (if you're a magus woman of enough prestige) > Waver > Kariya> Kayneth (if you're a magus woman of average prestige) > Kiritsugu > Kayneth (if you're a muggle) > a shit > Kirei > a country full of shits > Ryuunosuke.
With Kayneth, I'm not even putting all the fault on him, but his environment and especially his sadist of a sister will make you the more miserable the further down the ranks you are, and unbearable if you're a muggle. With Tokiomi that isn't really an issue because he lives at a place where he used to make the rules, and the Magi Association won't give a shit if he dilutes his backwater lineage. As long as he loves you you'll still be okay.
