Here is a quick overview of the three major products that are in the market today, Apple (HomePod), Google (Google Home) or Amazon's (Amazon Echo). Which one of these out performs the other? What other considerations should you be thinking about? Take a look at this article and see if this helps you to decide.
Me, I have already made my commitment to the Echo line of products. Each of the different product lines have their different pro's that might make you lean towards that product. If all you are looking for is good sound for your music, I would probably stick with none of these and jump back to Sonos. It has the widest flexibility but will make the biggest dent in your pocketbook. If you are looking for the add-on apps to make the unit a true assistant, then the Echo is probably the product you should be looking at. If you are heavily into Google products and apps then it might be Google Home. Lot's of things to consider.
