Smoothie King's "Hulk" or "Gladiator

Hey, I want to know you guys opinion on which smoothie from Smoothie King I should add  into my diet since I am trying to gain weight.

--

Here are the nutrional facts on two they suggested for me to drink.

--

1) "Hulk" has a lot of calories,  I can ask to add  45grams of protein on it (whey protein), but it comes with a lot of bad stuff. Best smoothie I ever tasted.

2) "Gladiator"definitely does not have a lot of calories, but it appears to be much healthier choice and has a lot of protein.

What would yall suggest I drink? "

I get a discount on these smoothies at my college and the store is really close to the college's gym, so I can drink a smoothie 30 mins before I go to the gym. Thats the main reason I want to add a smoothie from there into my diet.
