What is your favorite format?

I got back into MTG Arena about a month ago. It has been fun and nostalgic to get back into playing MTG. I was curious what format everyone is enjoying. Any suggestions on decks you enjoy would be appreciated as well! I tried Brawl, which I think is similar to Commander, but I can't test the deck out, and everyone I have played has basically destroyed me before I could even get a combo out, ha. I played a long time ago, and the only format I played was the classic 60-card deck.
