Unless you can qualify why, then it's just rhetoric. I've been there done it, have used various systems dating back to the 70s, and recommend it.
Fact is they're immensely popular for a number of reasons. There are pros and cons to any setup, but this is a winner.
Facts
a - alot of plastic is being used (plastic covered cables - plastic pulleys). Plastic all over this machine. Parts get old & snap. I've seen snapped rods & rod ends. Broken seat & seat rails.
b - thin gauge metal (13 gauge is the heaviest thickness) very shaky in it's connections where the metal comes together. Cheap tube construction allows for cheap manufacturing but it's thin nature makes for a very shaky design in the movement of the leg & lat tower.
c - foam rollers deteriorate in time. Loosely fitted & poorly attached.
d - Biomechanics - terrible! Points of resistance are to low for the average user. Bowflex was selling a chest extension as an option (should have come attached with the machine). The rods are not a very fluid movement. The Leg press movement is terrible & difficult to get into position. The squat postion is even worse.
e - easy of use. Early models required attaching cables to the lat & the leg ext/leg curl apparatus. Not easy for the beginner exerciser or women. Newer version is a little easier but stick lacks typical easy of use like a seceltorized weight stack. Most novice users can't figure out how to use the equipment.
d - Recalls....how many recalls has this product have on it? I know of three different ones currently active. One is for the pulleys snapping & coming loose where they connect to the frame. The second is the Lat Tower coming loose & falling down. The third is the back rest support coming loose & snapping.
I can keep going if you want.
