Anyone know the best pool algaecide for pool service?

I'm having a bit of trouble deciding which pool algaecide to go with and was hoping to get some advice. I've done some research and came across a few options like HTH Algaecide, Leslie’s Algaecide, and Algatec Algaecide. Has anyone used these before? Or is there another one you’d recommend? I want to make sure I’m using something effective that won’t harm the pool or equipment. If you’ve had good results with any of these or something else, I’d really appreciate your input!
