What Is the Best Dictation Software For Mac?

I can not type for long, so I need to dictate. I used to use Dictate for Mac, but it no longer works well with Mac. I used a headset to better eliminate background noice. I haven’t found a good substitute, including Mac’s built in dictation program. What are suggestions for the best dictation software and a good microphone/headset to go with it? I have macOS Mojave 10.14.3 and use PAGES, NUMBERS and MAIL mostly.
