Short answer: Yes, you can make very good pixel art animation in Spine.
Longer answer: The way to do it will depend to some extent on your engine (Unity, Gamemaker, home-made, etc) and the setup you are using. The biggest thing for us on Boss 101 was turning off some of the extra twizzles inside the Spine editor like linear filtering (options panel) and onion skinning (this is my personal preference). Also, and this is just a general game development thing - you will NEED to be able to look at stuff in your engine quickly. Spine (or any editor) is only good for the setup and overall feel. Once things are in the game you see the real deal so don't think Spine can magically do things like give you a perfect in-game preview (no editor I know of can do that).
Also, I really recommend animating on whole numbers for any pixel game. This means you animate to whole number locations like x=23, y = 56 etc versus something like x = 23.5, y = 56.2. You'll get much more reliable results. To be clear I am referring to making your KEYFRAMES fall on whole numbers. The in-betweens will probably be tweened by the engine to some fractionals but that's fine.
You can check out my links below for a look at the game we are working on. We've been using Spine from jump street and it has been a fantastic tool. Feel free to message me or mail me directly if you have some specific questions and good luck with your game!
