Hi mrmusic,
Yes … all of these are among the best quality/value in the country but they are also different in terms of the cost, the options they have available for re-arranging and exchanging layers, and some of the other features and benefits that are either part of each design or part of dealing with each manufacturer.
As you can see in post #2 here (and many other similar posts in the forum that ask how to make final choices) … the only way to choose between “good and good” final choices would be by talking to each manufacturer and deciding based on your own personal value equation and which of the differences between them are most important to you. There is no “right or wrong” or “better and worse” any more … just different and which one is best for YOU.
