For barbell, at those weights? Brand doesn’t matter. Decide what you want in terms of style (traditional lasso, figure 8, oly closed loop) and material (leather, nylon, cotton) and just find a brand that is cheap or whatever.

I use traditional nylon straps for deadlift. I don’t mind the longer setup of traditional straps, for a very secure hold. And people talk about cotton being more comfortable but I don’t think it makes a big difference, so I went with the more durable material.

Worth noting that I only use them when deadlifting at max effort (for me, multiple reps above 400 lbs). That being said, I also have chalk at the gym and generally use chalk above 225 lbs, and do hook grip between 315 and 405 lbs. That way I’ve gotten my grip strength up even while I won’t have to worry about slipping at max effort. But it also took years to get to this point, too.
