This is really frustrating IMO. It's been ten years now. DM's Guild has authors on it that have dozens of publications. Heck,
@M.T. Black has a whole bunch of FANTASTIC adventures - there's a pretty good reason he's a columnist here. He does great stuff.
This isn't the days of Web supplements. The DM's Guild stuff, or if that doesn't float your boat, Kobold Press, and various others, have years of experience with the system. It's not like 5e is that tight of a system that a couple of pluses one way or another is going to matter that much. It really does a disservice to everyone to not check out what's available. There are lots of fantastic short adventures.
I just ran Rats of Waterdeep three times this year with three different groups. Unbelievably fun.
