Here's a quick run down on the rye content in the mashbills of some of the major bourbon labels.
Jack Daniels: 8%
Early Times 354: 11%
George Dickel: 12%
Wild Turkey: 13%
Heaven Hill Bourbons: 13% (includes Heaven Hill, JTS Brown, TW Samuels, Evan Williams, Elijah Craig, Henry McKenna, Ezra Brooks, Yellowstone)
Very Old Barton: 15%
Old Forester: 18%
The highest confirmed rye numbers I have are for Four Roses. They have two separate mashbills. There will be a four digit code on most of their releases (except Yellow Label). If the code starts with "OE" it's 20% Rye. If it's "OB" it's 35% Rye. I would definitely recommend trying some Four Roses bourbon.
I don't have specific information on the content of Buffalo Trace or Jim Beam bourbons but Buffalo Trace does have a "lower corn" mashbill they use for Ancient Age, Elmer T. Lee, Hancock, Blanton's Rock Hill Farms, Virginia Gentleman, and Bowman Single Barrel that I believe has relatively higher rye in the mashbill than their other bourbons.
LDI bourbons like Bulliet, W.H. Harrison, and Redemption are all supposed to be "high" rye bourbons but I don't know how high that really is.
As to whether or not they are worth trying. That's kind of a personal thing. I'd recommend trying them in a bar if you can rather than buying the whole bottle.
I hope this helps.
