I love rye whiskey, and Old Overholt is a great value for the price! Definitely less sweet than bourbon, and I suppose you could describe it as less subtle than bourbon as well - not a bad thing, just different. If you've never had a properly made Manhattan with rye whiskey, sweet vermouth, and bitters you owe it to yourself to try one. A Manhattan is way too sweet (IMO) when made with bourbon as most places do these days, but just right with rye. Unfortunately most bartenders in my neck of the woods look puzzled when I ask if they have rye... if I'm lucky they'll say something like "uh, we have Canadian whiskey" but most of the time the only American whiskey they'll have is Jack Daniels or bourbon.

Last summer I got to try Catoctin Creek Distillery's "Mosby's Spirit", which is an unaged rye "white whiskey". It was a real eye-opener; it is a lot smoother and has a lot more flavor than you might expect when you're used to whiskey that's been aged in charred casks.
