The one major drawback is the power cord connection
Do you have a big problem?
I've owned 4 Kindles so far and they all perform very well.  The one major drawback is the power cord connection.  It is not durable at all and you have to be very careful not to move the Kindle while it's plugged in. I had to replace 3 Kindles in the last 2 years and thankfully it was under warranty.  I don't have the the new version HDX Kindle yet so I can't comment on those.
