Is Coma (by Robin Cook) as bad as Crisis (by Robin Cook)?

I suffered through Crisis because I dislike not finishing books. In the beginning the book was a page turner, really good pace, intriguing story, but it all fell apart very quickly. The story doesn't hold, there are so many incongruencies, the characters are so poorly developed. This was the first book by Robin Cook I've read in years – I think I read one or two when I was a teenager and I remember liking them, so I decided to get both Crisis and Coma on sale. But I was not expecting it to be this bad. Now I have Coma staring at me and I'm not sure if I want to suffer through it read it. I believe Coma is one of his best books and the story seems really interesting. On the other hand life is too short, and my TBR is huge lol Has anyone read the two books? How do they compare to each other?
