The deciding factors
The Prime TC is the value pick within KENT's own range: you keep the RO+UV+UF+TDS stack and the 20 litre/hour throughput, and you give up the water-recovery technology. If your supply is metered or tanker-fed, that omission matters and you should pay up for the Grand Plus. If you are on reliable municipal supply, the Prime TC does the same job for less.
Against that, Blue Star Aristo makes its case differently: The Aristo does not win on any single spec, and that is fine — it is a well-built, well-supported mid-range RO from a company whose service organisation is genuinely good because its commercial customers will not tolerate downtime. If you have had good experiences with Blue Star cooling products, that service relationship is a legitimate reason to buy.
Our practical advice: unless the KENT Prime TC'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.
