Canon lens mugs

Just looking to get one of them for a friend.

Are they all the same or are there better/lower quality ones, because there are loads of variations? Definitely want one with stainless steel inside.

Was considering these:

Hadn't seen these before, these are awesome! Look pretty similar to me.
There is a 70-200 f2.8 on there that would probably take the biscuit
