OSB vs Plywood for flooring

    I need to replace badly damaged chipboards on the entire floor with new boards. Stud walls have been removed and the floor joists are spaced about 40cm apart.

    I am considering to use 18mm T&G SmartPly OSB or 18mm Brazilian/Malaysian plywood (unable to source T&G plywood), and D4 adhesive and Spax screws.

    My main objective is to make the floor as solid as possible and avoid any squeaking. Should I use OSB or Plywood?

    If I used T&G sheets with the dimensions of 2.4m x 0.6m, would I need noggins on all edges; i.e. every 0.6m?
