Design-Build VS General Contractor

[Mithun Bondugula]

I have bought a very old house in Redmond. WA. This house has 70s kitchen and batch finishes. I am looking to get the place renovated - remodel kitchen, 2 bathrooms, recess lighting, open layout, popcorn ceiling removal. 

I have spoken a design-build company (LUX Design Builds). I also got a contact of a handyman turned General contractor - this person has worked with couple of my friends for over 10 yrs. 

I was told that the GCs are cheaper than design and build companies. What other differences should I consider? When would one go with design-build company as against a GC? 

Thank you in advance for you guidance.
