Templeton isn't bad. It's not the best Rye out there, but it's an enjoyable dram, and definitely worth a shot if you're in Iowa or happen to find some at a bar.
The Pappy Rye is overblown. It's alright, but doesn't deserve the obsession people have with it.
Baby Saz (or Sazerac, to most) is a nice, light rye, and mixes well. I almost always drink my Rye straight, or in a Sazerac, so I don't have much to say about mixing, but this one is pretty commonly used in mixed rye drinks. It's not expensive, and is nice.
People also like mixing Rittenhouse BIB (Bottled in Bond) - which is the only way I'd suggest using it - it's not a rye you'd enjoy drinking neat (probably) - it's pretty rough around the edges.
Lots of bars carry Michters Rye, unfortunately. I think it's the worst of the bunch. If this is the only Rye you've tried, well, you haven't really tried rye.
I almost don't want to do this, because I enjoy that Rye can sometimes sit on the shelf at a liquor store far too long, to await my finding it. But in the interest of the public good, here's a list of killer Ryes, that might change your drinking habits should you come across them:
Thomas Handy Sazerac
- Sazerac 18
- Rittenhouse 21, 23 & 25
- Classic Cask 21
- Willett (any of the Willet Ryes, if you're damned lucky enough to find them).
- Black Maple Hill 18 & 21 (or is it 23? It's the silver label). BMH is really Willett, with water added to bring the proof down to (I think) 90. It doesn't say so, but if you drink enough of each, well, it's pretty obvious.
- Red Hook Rye (this stuff is discontinued, as the store in Red Hook Brooklyn that sold it has closed - if you find it, you're getting it off a collector).
- High West Rye (A newcomer, but very nice)
There are also the Portrero Ryes, which are interesting, but I don't enjoy them as much as the above.
There are others, of course. Don't waste your time with the fancy-bottled RI - IMO, it's not worthy of your gullet.
Rye is more interesting than most bourbons (though there are lots of outstanding and interesting bourbons as well), more complex, and really grows on you once you give it a shot. It's been my favorite whisky for years.
If you find any of the above, go for it. Some are pricey, all are worth it.
