Gold Frozen Chest vs. Imbued Gold Frozen Chest

[Energizeric]

Sam posted the following:

Gold Chests drop one of the below:
• Breezaga Air Elemental Pet Egg
• Frozen Jewel Ring
• Snow Talisman Amulet
• Wintermancer Armor and Helm
• 8 Winterfest Tokens
• 16 Winterfest Tokens

Imbued Gold Chests drop one of the below:
• Tarlok Vestments Armor and Helm (the best gear from the event)
• Tarlok’s Heart Amulet
• Winter Star Ring
• Breezaga Air Elemental Pet Egg
• 40 Winterfest Tokens


What I would like to know is if there is any difference between these two chests as far as the chance to get the Breezaga Air Elemental Pet Egg. I realize the Imbued Gold Chests have the Tarlok gear which is much better. But as I already am holding more than 200 Tarlok items in my inventory, I don't need any more and am more interested in getting this pet egg. So is it best to just open the Gold Chests or should I craft and combine 5 of them to make 1 Imbued?

Perhaps a developer can advise? I'm sure I am not the only one with this question.
