Both systems are great in their own ways
The air itself is also being cooled in the ESS kit, the real difference is the heat exchanger is in the manifold and it uses liquid to cool the air instead of ambient air cooling the air. Liquid to air charge coolers as a rule can be much smaller and compact since the heat transfer from air to liquid is more efficient than air to air. No one way is better per say however liquid to air charge cooling is becoming more popular these days due to packaging issues under the hood.

The BMW N63 V8TT (550, 750, X5, X6), S63 V8TT (X5M, X6M, M5), and N74 V12TT (760) all use liquid to air charge cooling.
