The equal-spin pairing state, the so-called A-like phase, of superfluid 3He in aerogels is studied theoretically in the Ginzburg-Landau region by examining thermodynamics, and the resulting equilibrium phase diagram is mapped out. We find that the ABM pairing state with presumably quasi-long-ranged superfluid order has a lower free energy than the planar and ``robust'' states and is the best candidate of the A-like phase with a strange lowering of the polycritical point observed experimentally.
