Short answer
The Prestige Astra 750 Watt Mixer Grinder is the best overall of these six mixer grinders with 750 W motors: it has five jars, a copper motor, overload protection, ISI certification and a 2-year warranty on the product and motor. The Bajaj Military Series Rex 750W has the longest list of warranty terms. The Philips HL7756 states the most operating detail.
The Prestige Iris, Crompton Ameo and Preethi Blue Leaf Diamond sit between those. The table below sets the six side by side.
The Prestige Astra 750 Watt Mixer Grinder adds a fifth jar to the Iris layout. Alongside three steel jars and a juicer jar, it carries a Mix-O-Keep jar. Prestige makes the Astra in blue.
The jars stack for vertical storage, the maker says. It also says the sturdy jar locks and leak-proof lids keep operation mess-free.
The Philips HL7756 Mixer Grinder 750W states how the motor behaves. It runs at 23000 rpm with no load and 13400 rpm with load. The maker lists 25 minutes of continuous grinding.
The three stainless steel jars run from 1.5 litres down to 0.3 litre. The maker lists a smaller working capacity for each, down to 0.2 litre. Philips says rubber gaskets on the wet and chutney lids give a tight, leak-proof fit.
The Prestige Iris 750 Watt Mixer Grinder has a copper motor and four jars. Three are stainless steel and one is a transparent 1.5 litre juicer jar. The steel jars match the Philips sizes, with the smallest given as 300 ml.
Prestige says the overload protector cuts power if the motor overheats. The maker also says the lids are leak-proof and the jar locks reduce vibration and noise.
Crompton says the MaxiGrind motor in the Crompton Ameo 750-Watt Mixer Grinder can grind hard ingredients like turmeric and whole black gram. The three stainless steel jars come with lids.
The maker says the motor carries an overload protection feature. Crompton covers the product for two years. It covers the motor for five.
The Bajaj Military Series Rex 750W Mixer Grinder has a 750 W Titan motor and four jars. The liquidising jar holds 1.2 litres, the grinding jar 1 litre and the chutney jar 0.4 litre. A 1.5 litre juicer jar with fruit filter completes the set.
Bajaj says its Military Grade jars give unbeatable toughness. The dry jar has a 2-in-1 function blade, and the main blades are called DuraCut.

Begin with the jars. Prestige and Bajaj include a juicer jar. Philips, Crompton and Preethi give three grinding jars. If you juice often, compare these against our best juicer mixer grinder guide.
Next, read the warranty. Crompton, Bajaj and Preethi state five years on the motor. Prestige states two years on the product and motor, and Philips states two years on the product only.
Safety matters too. Four of the six models state overload protection. The Bajaj and Preethi pages do not. The pages leave out other points as well. The Bajaj and Preethi pages give no speed settings, the Crompton page gives no blade detail and the Philips page gives no ISI certification. None of these gaps proves a flaw. They only mean you should confirm the point with the retailer.
Storage is a minor point. Only the Astra's page says its jars stack for vertical storage.
Choose the Prestige Astra as the best overall: it has the largest jar set, and its listed motor, speed control, overload protector and warranty match the Prestige Iris. The Iris leads our wider best mixer grinder guide because the Astra is not compared there. Choose the Philips HL7756 for listed speed and run time. Choose the Crompton Ameo for the five-year motor warranty and a plain three jar layout.
The Bajaj Military Series Rex 750W and Preethi Diamond suit buyers who value warranty and service terms. For the wider field, see the full mixer grinders section.
