Warren Buffett is a very rich man who likes to save his money and not spend it on fancy things. But he still has some expensive stuff, like a special card that lets him borrow nice planes when he needs to travel. He also lives in a big house in Omaha, where he was born. Some of the other things he owns are worth a lot because they are very old and rare. Read from source...

1. The title is misleading and sensationalist, implying that Warren Buffett has a double personality or contradicts his own values, when in reality he simply enjoys some luxurious items as part of his wealth portfolio. A more accurate title could be "Warren Buffett's Less Known Luxurious Possessions".
2. The article does not provide any clear definition or criteria for what constitutes a lavish thing, leaving room for subjective interpretation and personal bias. For example, the author considers NetJets membership as luxurious, but others might argue that it is a practical and efficient way of traveling for someone who runs a multibillion-dollar investment firm.
3. The article focuses mostly on the material value of Buffett's possessions, rather than their historical or sentimental significance. For example, the author mentions Buffett's collection of silverware and china from the Sun Valley Lodge, but does not explain why he chose to acquire them or how they relate to his personal or professional interests.
4. The article uses emotive language and adjectives that convey a sense of admiration or envy towards Buffett's possessions, such as "lavish", "antique value", "secluded", "exclusive", etc. This creates a tone of bias and detraction from the main purpose of the article, which is to inform readers about Buffett's lesser-known aspects.
5. The article lacks credible sources or evidence to support some of its claims, such as the one about Buffett owning "one of the largest collections of historical documents in the world". This statement is not backed up by any reference or citation, and appears to be based on hearsay or speculation.
6. The article includes irrelevant or unnecessary information that does not contribute to the main topic, such as the list of best stocks and ETFs, penny stocks, etc. These sections seem to be added for SEO purposes or to attract more clicks, rather than to provide value or insight to the readers.
7. The article ends with a call-to-action that encourages readers to subscribe to Benzinga's services and trading tools, which creates a conflict of interest and undermines the objectivity and integrity of the journalism. This also suggests that the article is more of a marketing piece than an informative one.
