Mali are not the best Nigerians are!
I voted for Blue Tounged skink. They are just so odd looking. Matlock....oops Macklots python get to big and nippy! Vines are nice but hard to handle and are escape artists. If you chose a Desert Hairy scorp instead of a Emp. I would have chose that but you have to like inverts to really enjoy them. If you want a hands on type of pet, the Uro. or Blue would be the best choice. I didn't like Uro's until we got some. Lets face it most of us would be happy with any of this!
Good luck in your decision and let us know what you end up getting. But personally I would suggest a box turtle once you get one everything else is boring!.
