How good are MJ Models/Inno 64?

I have been collecting minigts for a while and have 1 poprace (aston martin vantage gt).

I love minigts for their detail and poprace for its built quality(feels heavier than minigt) and has moveable parts too in other castings.

I have seen reviews stating tarmac works are hit or miss.

Recently came across MJ Model porche gt3 rs and BMW g82 M4. They look great but how is the quality?

I have also been eying Inno64. How good are those?
