In my opinion, a diversified index ETF will be a lot better than solely investing in Apple. By diversifying, you will be able to reduce concentration risk significantly. Index investing will probably be the best for most investors.
It's all branding. Like how most people think diamonds are the rarest/best gemstones especially for engagement rings cause of de beers. Would you say that Samsung is not a prestigious brand? Especially their galaxy s and note lines? In my opinion, apple is one of the most user friendly but only if you're into their ecosystem. Otherwise I prefer the customizability of android.
