With regards to climbing shoes I would say there’s super cheap crap, and that as long as you don’t buy that, personal preference is more important than anything else. Professionals will often be using the same shoes as people with a couple months of experience.
I don’t know the first thing about climbing, but I assume there is good stuff, and then super expensive top notch stuff.
My comment is not an argument against getting decent or good equipment.
