Pretentious would be a good word to use. It doesn't sound like swear word, unlike some of the other suggestions here, and adjectives are less harsh than nouns. I guess it depends what you mean by "stronger" - "insulting"? "more definitive"?

• condescending
• patronizing
• lordly
• lofty
• snooty
• disdainful
• toffee-nosed
