Relaxed Intensity
A less experienced DM is wise to run published adventures to learn the ropes, and as we know the CR is erring on the easy side, which is actually great for new DMs. Of course, the first encounter in LMoP is a textbook case of throwing DMs in at the deep-end, but as I said, WOTC sucks at teaching the game.
I think when you're starting modules are often way too big a bite off the apple. Something like Matt Collville's 3 room dungeons with a small supporting narrative are way easier to get going with.
