[Unanswered]  Xmas Recomendations for my 2 boys

Hostileblade, what does that have to do with anything? Anyway, I recommend these:
For TT:
Drain Fafnir
Nightmare Longinus
Random Booster Vol.6 (x2)

or Hasbro:
Xcalius
Roktavor
Drain Fafnir
Lost Longinus

In General:
B-33 Beystadium Standard Type
LR String Launcher (x2)

You'll either choose from the TT or Hasbro list, In General is what you should get regardless of the other two. From either list there are two dragons, and even though I don't personally know your sons, I'm pretty sure dragons will appeal to them. Random Boosters are in there for reasons stated in other posts. On the Hasbro side, Xcalius and Roktavor provide good attack combos and for sure attack is more appealing to many people than stamina or defense
