Mini Whiskey

What is the best whiskey to get someone who likes Jack Daniels?
My boyfriend and I are doing a children's party to reach the mark Three months. Nothing too special, just dinner and a gift exchange. It is high alcohol consumption, and when we always order from a nearly terminal and coke. Whiskey is your favorite drink. So I thought I would buy him a bottle of something for home. I will not go take it since I know there is a better quality whiskey in there out, but I do not know anything about whiskey, for starters. Therefore, for those of you who know Jack about whiskey, please enlighten me. What should I look? He drink alone or with ice at home. Only ever drink it with coke when we left.
No sense in spending too much money, if you are going to be pouring Coke into it. But if occasionally drinks with ice or clean, you buy some ROYAL CROWN.
