SSAA only adds blur.
Applying 9xSSAA to a 1xIR image won't make it any better than 2xIR (or even 1.5xIR) with no SSAA.
1xIR looks like a blurry mess, 2xIR looks 'HD', while 1xIR + 9xSSAA looks like a smoother version of the blurry mess.

Increasing the internal resolution adds more sharpness and detail to all 3D objects. It greatly improves the texture quality as well (acts like an anisotropic filter).

Internal resolutions over 3x are still useful on FullHD (1080p) displays.

4xIR on 1080p may not improve the sharpness of static images that much (like the jump from 2x to 3x), but it definitely improves the quality of objects at *far distances* and removes some of that annoying shimmering (aliasing artifacts) in dynamic scenes.

6xIR (or 2x fractional) would be ideal even for 1080p screens (not just 4k QuadHD displays). Just try the custom resolution feature in PCSX2, set the X and Y res to 2x your screen resolution and enjoy the solid, artifact-free graphics.

There are many games that still need more than 4x IR on a 1080p display (DKCR, for example). With 4xIR, the image quality is still far from 'perfect' (noticeable even on a small 21" monitor !). 4x IR + 2x MSAA (D3D11) looks much better, but MSAA adds glitches (white dots around polygon edges).
