Is Thermador that much better than Bosch?

Thermador is not that much better than Bosch for most appliance categories, as both brands are owned by same parent company BSH Bosch und Siemens Hausgeräte GmbH and share many internal components, with Thermador being luxury sibling positioned above Bosch with premium features and higher price. Bosch is German brand founded in 1886, known for excellent engineering, quiet dishwashers at 44 decibels, reliable refrigerators, and good value premium appliances made in Germany and US, priced moderately at 800 to 1,500 dollars for dishwashers and 1,800 to 3,000 for fridges. Thermador is American luxury brand founded in 1916, owned by BSH since 1998, positioned as ultra-premium with professional-style ranges, 22,000 BTU burners, built-in coffee makers, and luxury features like steam ovens and column refrigeration, priced 30 to 50 percent higher than Bosch, for example Thermador dishwasher at 1,500 dollars versus Bosch 1,000 dollars with similar cleaning but more premium racks and styling. For dishwashers, Thermador and Bosch share same wash system and cleaning performance, with Thermador offering slightly better racks and drying but not dramatically better cleaning. For ranges, Thermador is much better than Bosch with more powerful burners and professional styling, as Bosch focuses less on pro ranges. So Thermador is not that much better than Bosch for dishwashers and fridges, with similar internals, but is significantly better for professional ranges and luxury features, making Thermador worth it for luxury kitchen aesthetics and cooking performance, while Bosch offers better value for most buyers.
