taking into account the training formula
(BaseValue + Sum of StatBonus) * (1 + MoodMultiplier * (Sum of MoodEffect)) * (Sum of TrainingBonus) * (Product of FriendshipBonus) * (1 + 0.05 * NumberOfSupportCards)

lets put someone like LB0 Suzuka which is a great card vs LB4 Brian

Suzuka has 25 friendship bonus, 45 mood effect, no speed bonus and no training effectiveness, in a scenario of lvl 4 speed training where suzuka shows up as a rainbow with another random support we get
(13)*(1+0.2(1.45))*(1)*(1.25)*(1+0.05*2) for a total of 23.05875

if we plug in Brian with 30 Friendship bonus, 0 mood effect, 2 speed bonus (it applies to the BASE, making it very strong), and 5 training effectiveness under the same conditions we get
(13+2) * (1 + 0.2(1)) * (1.5)*(1.3)*(1+0.05*2) for a total of 38.61, a sizeable difference

you have to also take into account that mood effect also applies to negative moods, so it amplifies the -10/20% effects of bad and awful mood.
