My gym has hand selected pieces from Atlantis, Prime, Hammer Strength, Cybex, Arsenal, Body Masters, Nautilus, Flex Leverage, Kore Strength, Gymleco, Rogers Athletics, Life Fitness, Magnum, Precor and Panatta (probably missing a few).
All of these are not random pieces but the best pieces from each line. Not sure how long ago you used Panatta, but they are fantastic machines. They are probably the smoothest machines and basically an improved version of all the classic pieces with better movement but more importantly improved path/motion to really enable (almost force you to use correct form) islotating the target muscle. Out of all the machines they get used the most.
Now if you want to talk about overrated, the most overrate piece is the Nautilus Pullover. Yes we have the orginal Dorian one. This piece is almost a myth due to it's reputation built up by people who never even seen one in real life, only have seen Dorian use it in old videos and are parrating about how they know some guy who used it and says it is amazing. And those that have the opportunity to use it, I would guess 90% of them don't even know how to or actually target their lats using it. Not saying it's a bad machine, but there is nothing magical about it. It is not what built Dorian's back.
