Without the 32MB of ESRAM you have 12 gpu compute units and 8 cpu's all sharing the same pool of memory of low bandwidth DDR memory. The ESRAM is there to help solve that issue but there is only 32MB of it. It's a clear limitation. Cache memory is there to remove latency issues and help coordinate use of bandwidth but there is clearly an issue with the xbox one, cache can't create extra bandwidth.
Also remember both GPU's have compute functionality. So the extra power of the PS4 GPU can be utilised for additional compute power if necessary which again means for CPU intensive games it can have an advantage. Obviously if the GPU is used for this then actual GPU work has to be reduced but there may be games where the PS4 advantage is an improved physics engine or more characters on screen or improved AI.
The PS4 is just a much more powerful design and will be capable of greater things than xbox one.

The eSRAM isn't a limitation. Developers don't have to use it, they have a choice.
If developers make use of it, they get a performance boost, how could that be described as a limitation when it increases performance?
Is it as Ideal as the memory set-up in the Playstation 4? Heck no. But it's still not a limitation.
Fact of the matter is both systems are going to have games that look downright fantastic, eSRAM or not. (Granted at only HD resolutions. Ugh.)
In the end, most games won't be any different across platforms, save for some minor details (That people will most certainly blow out of proportion), most developers use 3rd party game engines and don't optimise for any specific platform to a massive degree, it's only the first party developers who generally push the envelope.
But if you are indeed worried about graphics and performance, get a PC and stop stressing.
