MoristarHonestly it's probably the same kit, minus the branding and markup, since the iFixit tools are all just stuff you can get from AliExpress and Chinese eBay shops...
Tex-ArozziiFixIt Tools are really good, but being those unbranded it seems that they are either selling this without the branding to make cheaper or those might be products with some small imperfection that may have been refused by iFixIt.
Not sure about the quality in this case but would be cautious.
