No, Benicio to Moegura I don't recommend.
Benicio will usually have no real effect, Moegura has 1 Extra Damage and his ability helps him win in low pill battles just as easily. Also, against Power Manip with Ability Moegura can still match up.
The issue I take with Benicio is that he usually will have no ability, so I do not recommend him.
Jalil to Rodney preferrably
The rest is golden
Buba > Greow.
Obviously Greow is going to be better against SOA, that's generally how stop:ability characters function. Generally speaking there is not enough SOA in ELO to justify using Greow ahead of the other 4* options, particularly Buba in mono. This is even more the case in lower levels of ELO where the deck trends are more random.
If you want to use a stop:ability card, I'd say that Mindy --> Ashiko is the way to go.
I also wouldn't recommend using Jalil over the likes of Rodney, Radek and Scopica (who is perhaps the most similar in function).
