Is the PS4 Sony's Most Successful Console to Date?

[Signalstar]

I guess this question on how you define "Successful".

Do you think it can be reasonable argued that the PS4 is Sony's most successful console to date? The obvious other contender is the PS2. It is quite apparent that the PS4 won't be able to match the PS2's hardware total. But is that the only way to compare which of the two even numbered consoles is more successful.

The gaming industry is a lot different than it was in the PS2 era. There was no digital software distribution or paid subscription services both of which are huge parts of Sony's gaming business now. The PS4 has sold more software and made more profit than the PS2. It won't ever reach the mass market ($129) price of the PS2.

Nor was the PS4 ever as dominant against the competition as the PS2 was over its contemporaries.

Sony's 1st party software has also  achieved a new level of acclaim and sale success during the PS4 era.

So what do you say? Is the PS4 Sony's most successful console or is PS2 still the king?
