On the rocks is fine for literally anything under $100 don't let anyone tell you anything different I've had $400 bottles that require eye dropper measured amounts of water added. I've only had a few things that were really better neat, we had this one bottle that was aged in spiced rum caskets and it was like drinking both things at once, that was good neat.
I drink a lot of Blanton's but until you get accustomed to it you might not want to spend that much. I have a bottle for every price range whether I want to spend $30, $40, $50, $60 etc.
Makers and bulliet, eagle rare are all fine for cheap stuff. Buffao trace is okay. Tin cup is great for a few dollars more. Woodford reserve is good. Blanton's is great. Elijah wood has one batch that's okay but the others are meh.
