I think the Zone bars taste really good, they've got rice krispies or something baked into them, they're good and crunchy. Balance bars have about the same nutritional profile, they taste really good, I reccommend all flavors, my favorite ones are Mocha Chip and the chocolate raspberry ones. I like Kashi GoLean Bars A LOT but they're rather sugary which is probably why they taste AWESOME, they've also got the crunch/chew factor. Last year I got hooked on the Genisoy bars, especially chocolate mint mmmm yummm. If you're looking for something that's more hardcore, like higher protein and no sugar/low carb then I reccommend Doctor's CarbRite Diet bars in the chocolate raspberry flavor. I tried that the other day. Good smooth texture, not dry, pretty good. As for shakes, I have the Mass Quantities Triple Threat 360 in both flavors (vanilla and chocolate) and I like the taste a lot. Pretty sweet, mixes thin with water and are especially good with fruit and soy milk and ice to make fruit smoothies. I also liked chocolate flavor Grow! by Biotest. If you want a shake with both carbs and protein, in other words, a meal replacement, you might like Myoplex Light. I think its 20g carbs and 24g protein. The Cappucino flavor is very good. The other flavors aren't so hot. The texture is sludgy though.
If you're looking for convenience I'd stick to bars, however, as shakes require a blender.
Oh, and by the way, these things taste bad in my opinion: Just Whey protein powder by SportPharma (blech), Myomax protein powder (not to be confused with Myoplex), and Met-RX bars because they have this dry alcohol-y aftertaste and a yucky overly chewy sludgy texture to them. Though, the cookie dough flavor is alright.
