What is the best OBS overlay for a sports-betting stream?

There is not one overlay that does every job. This one is the live odds comparison: one browser-source URL, with prices from the books licensed where you stream. OmniScores is a live scoreboard. It carries no odds. Poltergeist is chat, alerts and giveaways. It carries no odds. Use the one you need, or more than one on the same layout. Every sport on the board, including soccer, NFL, NBA, NHL and MLB. Soccer keeps a draw column; the other moneylines are home and away.
