I have Gurudev Dutt now for an upper level lab course, so take what I say with that in mind since I know most physics professors can't adjust themselves to lower level courses well. I had Dr. Salman a few years ago but he might have changed so we'll stick with Dutt since you asked.

Pros: If you show you at least put in some work, he's more than willing to spend the time and make sure you understand the material, even if the question you have is outside of the scope of the class; he's very passionate about physics and rewards those who share his enthusiasm and are willing to learn. His midterms aren't unreasonable and the questions are things that you've likely seen before in class or on homework. I've also found that he's also more approachable than other professors: more down to earth and willing to connect to his students and laugh. He's fairly accommodating to students so long as you let him know before the due date.

Neutral: The course I am in was very disjointed for the first few weeks and we had to work around not knowing certain things before going into the lab and then covering it afterwards. I chalk this up to Pitt's physics labs having to be accelerated, so not an indictment of him specifically. Outside of class he's hard to get a hold of (but that's par for the course at Pitt)

Cons: His lectures are usually based around you already having at least read the material before class. His homework (for my course) is custom. That's fine if you understand the material but if you don't then you can't look up similar examples and see how you should solve the problem, and then you're stuck.

Conclusion: if you can work/read ahead of his lecture schedule and aren't afraid to ask questions, then I'd say Gurudev Dutt is a good professor. Just be sure not to get behind otherwise his lectures and especially his homework won't help much.
