I'm going to go out on a limb and say that the Focusrite Vocaster interfaces are the most complete, entry level podcast/streamer interfaces you can buy. They come in at a very affordable price as well. The Vocaster One is $199.99 and the Vocaster Two is $299.99. They also have a bundle package for each, which come with a Microphones, Cable, and Headphones for $299.99 and $499.99 respectively.
What's special about these interfaces, vs say a Scarlett Solo or Scarlett 2i2?
Let's start with the Vocaster One. First there's the auto gain setting, which lets you push a button, talk into your microphone for about 10 seconds, and then it sets the appropriate gain for you. Perfect for the person who doesn't have much experience making a podcast. Next is the mute button right on the front of the interface, which allows you to cough, or make other disgusting noises, and not have them reach your pristine recording. There's also a TRRS input for your cell phone, to capture phone calls, and another connection that allows you to run the audio out to your video camera. The software also has two loopback channels, which allow you to cue up audio from various sources on your computer, so you can play your prerecorded intros, soundbites, and more.
The Vocaster Two adds to those features with a bluetooth connection for your phone, which allows you to access phone calls and more from your phone. It also has two microphone preamps and two headphone outputs with individual volume controls for both channels, as well as individual Mute, Autogain, and Enhance buttons so each person can set and control their sound, and headphone volume.
What also makes them special is the layout of the devices. The buttons and knobs are all located right on the top of the unit, with easy access for each podcast host.
Lastly, did I mention it has enough gain to amplify the Shure SM7B and other low output broadcast microphones? That's a huge bonus, as you don't need something like a cloudlifter. You can take that $150 and put some gas in your tank. Inflation, am I right?
Pixel Pro Audio highly recommends these interfaces for streamers, and single and dual podcast situations. They sound great, they have all the features you could want, and that enhance button actually sounds really good.
