Of course, you mentioned similar websites but I think they have different purposes compared to Pangoly. PCPartPicker offers a huge set of components with different stores so you can find the best price available for almost anything, but it struggle with users having little building experience that are trying to find what's the current best build options for their budget. On the other hand logicalincrements offers a nice viewing experience of components tiers but it lacks building customizations. I think having another option and point of view is not harmful at all :)
