All adaptations were identical to the paperback versions.
From a nostalgia point of view yes; they can be found quite cheaply last time I looked. The hardbacks are the ones too got or really. The stories differ from what you see in screen, as the authors were sent first draft scripts; something they were not happy about.
About 10-15 years ago I found several of these in a used bookstore here in America. I snatched them up since back then I'd only seen four episodes. I always wondered how they found their way across the Atlantic. I did read a couple but don't remember they compare to the actual episodes. Some tv show novelizations are based on early draft scripts or the author adds material so the stories flow together and are less episodic. I think some of my copies have different covers than those here. I like the cover for Blind Run. The boys look ready to do some serious damage to evil doers!
Going through some boxes today and found my copies of The Professionals paperbacks. I have 3,4,5,7, 8-15. I have more than I remembered. I am still curious about how these crossed the Atlantic to end up in a used bookstore in my part of the world. I'm glad they did I am just curious.
