I had this same experience. In 2010, I decided to buy the Captivate over the iPhone 4 after reading a bunch of reviews online. IIRC, I bought it right when it was released, which almost exactly coincided with the release of Froyo. After four or so months of putting up with a laggy interface, cheap (feeling) build quality, and no software updates in sight, I sold it and finally bought that iPhone 4, which I used for the next 3 years.

Recently, I decided to give Android another try and went with the Galaxy S4 when that came out. I was pleased with how far the OS had come since Eclair, but it still felt less responsive than even my 3-year-old iPhone. As for the build quality, that's my biggest regret in buying a Samsung product again. It's hard to beat the feel of an Apple device, but at least the Nexus 4 and HTC One are trying.
