well, Maker's is a wheated (or wheat heavy) Bourbon - and if you didn't like it much then I suggest you stay away from the Van Winkle and the Wellers as they're wheaters also... Granted, I don't like Makers either and I love the sh*t out of Van Winkle whiskey, but just understand that they're categorically similar to Makers...
I suggest a rye'd (or rye heavy) Bourbon, which is nearly all Bourbons other than Makers, Weller, and Van Winkle. Common and moderately priced choices are Wild Turkey 101 (or Rare Breed), Elmer T Lee, anything from Four Roses (I prefer the Single Barrel), and so on. There are 30 or so pretty good to great ones amongst the rye'd.
Give Elmer T Lee Single Barrel a shot; it's particularly enjoyable and less harsh than most. ~$30/750ml
and a big +1 to the George T Stagg if you can find it. It's barrel strength and amazing, IMO.
