Post-Interlude Jeanne is, with some luck (and maybe some external help from CEs), capable of gaining 100% by each NP Saber Alter will use, and can also cleanse the DEF debuffs she gives regularly. Merlin's is tied to his skill (which can only be cycled faster using Tamamo) and Fuyuki Memorial Saber Alter's AI has a tendency to focus fire on Casters in general, which means keeping him alive can be a problem.

So under a lot of circumstances, yes, Jeanne is the better option here.
