Frank Elements looks great until you actually look at what they do to the version of ACR that is included with Elements. The the link to the comparison which you so kindly posted on the other thread.
The Tools Photoshop Elements does not have:
Color Sampler Tool
Targeted Adjustment Tool
Image Adjustment Tabs Photoshop Elements does not have:
HSL / Grayscale
Having used the full range of tools in the CS version of ACR, could you honestly say that you never use any of those tools? Also although Elements now almost totally manages Layers and more importantly Layer Masks, it mostly only does so in 8 bit colour, so you are again limited by what range of colour adjustments are supported.
It strikes me that Adobe have positioned Elements so that they get you hooked on the Adobe way of doing things, and then once you start to fully explore the limits quite quickly show up. The crippled ACR would not be so bad if you could at least go and do the remaining colour correction in the PS editor in 16 bit. Or the limitation to 8 bit would not be so bad, if the colour and correction tools were available in the ACR version.
The current best answer seems to be Lightroom, as with the full power of the RAW converter for the majority of users that covers between 90 and 95% (or more) of the processing that they are likely to do, and the rest can be done in Elements, as the 16/8 bit limitations are not such a problem when you are coming form the full featured RAW converter. I can see a point coming soon when Adobe may actually do us all a favour and integrate the Elements (maybe with full 16 bit support) pixel editor into a "Super Lightroom" product, for those small professional / advanced amateurs for whom CC is an OTT option. This way you have still captured them and CC is still there as the upgrade option.
