Nefaria will cover different opponents to your current r3s.
Titania is a smash'n'mash champ - really good, but basically there's very little she'll bring to the team, with Hulk and Silk already at r3.
Ham is great, and would be a decent choice; but there are very few champs he'll be good for that Deathless She-Hulk isn't already good for.
Nefaria brings control to the team; and can manage new opponents with Regeneration/Power gain more effectively than Photon, and in a different way to Deathless She-Hulk.

Ham is the fastest and best defender (in some cases).
I would go nefaria here because he's more versatile imo.
