I'll give my 2 cents, I don't know the jap names well, so bare with me.
Smugleaf: It's meh decent exp gain and decent move pools, It's middle tier.
The Doggy =D: Meh move pool, but it's exp gain is amazing and it's got good stats, High tier all the way!
Money Trio: Good for the first gym but after that it's exp gain is to low to be good.
Zebra: Frail, bad exp gain and no good moves for awhile. Just bad.
Bidoof Clone: Good HM slave, that's about it imo.
Rare pokemon that appears on every route and is pink + looks like a digimon (lol) : Eh it's not that good, rare yes but it lacks power.
