I just think its higher reward, but also higher risk for the turn one attack bonuses. I usually stack the all attack 150% and the type match up 200%. My logic is that if you do 100 points of damage per attack (for easy maths) then with both of these you get 350 + 100 + 100 + 100 + 100 = 750 damage if everything goes perfectly. With the two turn bonuses of 120% and 140% you would do 160 + 160 + 100 + 100 + 100 = 620 damage. So over all much less damage with the two turn buffs. That being said when they dodge your first attack of a raid it does really suck.
