I'm signed into 6 accounts right now, but I only visit 3 regularly (and Slack supposedly no longer keeps all teams in memory if you're not looking at them), and my average energy impact is 10.07. That puts it solidly in the #2 spot (with #1 being Xcode, which makes sense because I'm compiling all the time). I currently have 8 Slack Helper processes, one of which is sticking around 6-7% CPU, but the others are between 0–1%. Slack itself is around 4% (this is without me interacting with it, and with no animated GIFs visible on the screen right now). FWIW the impact of animated GIFs (including animated custom emoji) is pretty high. Switching to a channel where there's 5 tiny animated custom emoji pushes CPU usage up to 18–20% for Slack Helper, pushes Slack itself up to about 9–10%, and makes my Energy Impact jump to 40–50 (which is insane).
