Question about rewards

Finally i can post because i don't know what's happen, but in this forum I can't connect my user normally, and sends  me (every time) a long message of rare numbers and symbols. But well, it was not what I was going to talk about.

In this season i was 36 (i think, i had the cactus avatar ''Prickly Pear''), when i opened the piñata, i received 5 packs, i had the Sunflower piñata. But i saw the instructions and said that Taco League have the same reward... that's my doubt. If i get for example 45 in the Taco League, i will receive only 5 packs at the final of season?  What would be the difference? or there are no difference?  there is not much incentive to get to the next league?
