What effect can using EANx have on dive experience compared to air?

Using Enriched Air Nitrox (EANx) can indeed lead to faster recovery time after dives compared to regular air. This is primarily due to the lower percentage of nitrogen present in EANx, which reduces the overall nitrogen absorption in the body. Since nitrogen is the gas that can lead to decompression sickness (DCS) when excessive amounts are absorbed during dives, using a gas mix with a higher percentage of oxygen and lower percentage of nitrogen can aid in minimizing nitrogen buildup in the tissues.

As a result, divers often experience shorter surface intervals and can potentially dive more frequently without the same level of fatigue or risk of DCS that might come from diving with air. This shorter recovery period is particularly advantageous for divers who plan multiple dives on a single day or are engaged in a diving tour.

While other choices mention factors that are certainly relevant to dive planning and experiences, they do not reflect the core benefits associated with the use of EANx specifically in relation to post-dive recovery.
