I and my wife had both. Bastille day I came down with the main whuhoo flu, and just a month ago with the other. The other (delta) was like a common flu. Headache and joints ache and fever. The main thing was a severe respiratory type of illness. As well as the smell thingy.
2 people at my husband’s place of work just had it, one had gastrointestinal symptoms and had a rough week, but is better now, the other had a headache and fever for 3 days and feels fine now. He had covid last winter so I’m guessing it’s the other strain. That’s assuming the tests are even accurate. No one in the household of either person caught it.
