SP-M05 Or similar

Hey Guys

I am looking to buy a 29” hardtail frame from AliExpress. I’m just looking for a bike to do some distance on, classic XC race build.

My question is that is there any difference between the brands that seem to be selling the same frame? This frame appears to be identical across all four brands, are they just all coming from the same factory or is there any structural difference?

Or can anyone else recommend a tried and tested frame to use as a base.
