The deciding factors
The Aura is Aquaguard's answer to the wellness-feature arms race, and it executes it better than most: the copper and alkaline stages are both switchable, so you are not locked into either. Underneath, the purification is the same reliable 2,000 ppm RO+UV+UF stack as the Delight NXT, with a slightly larger tank and faster throughput.
Against that, KENT Supreme Alkaline makes its case differently: Let me be straight about what you are buying. The RO, UV and UF engineering here is KENT's proven stack and it is genuinely good. The alkaline stage does what it says — output pH lands in the 8.5-9.5 band. What it does not do is deliver the health claims that surround alkaline water online. Your stomach is strongly acidic by design; systemic blood pH is tightly regulated regardless of what you drink. There is no good clinical evidence that drinking alkaline water changes health outcomes in healthy adults.
Our practical advice: unless the Aquaguard Aura's specific advantages match a real constraint you have — tank size for long water cuts, a higher TDS rating for brackish supply, hot water you will genuinely use — the cheaper unit is the better purchase. In this category, paying for capability you will never use is the most common way money gets wasted.
