I strongly agree - I started teaching from slides and shifted more and more to blackboard and chalk.
I found that they can also be combined well by showing a slide that gives some guidance where "we" are in the material, supplemented by writing and drawing on the blackboard to explain one or more bullet points or statements from the slides, and to answer student questions.
This also forces students to take additional notes, which helps them per muscle memory.
