AGA has more to it than just the colours on screen. Yes, the maximum is 256 colours, but that will often be very slow. 64 or 128 colour modes also needs AGA (EHB mode aside), and AGA will also allow things like dual playfields with 16 colours each (ECS only allows 4 colours each), sprites up to 64 pixels wide (ECS is only 16 without combining sprites), and subpixel scrolling. So you can have a game that is still only 32 colours but requires AGA for the 64-pixel-wide sprites or super-smooth scrolling for example.
And then there are games that specify AGA simply because they need 2MB of chip RAM - they'll actually run on an ECS machine with 2MB of chip RAM, but such machines were probably rare amongst the gaming target market.
