I've had this rack (along with the extension) for over 5 years and love it. The T3 2x3 tubing is underrated because while it might not accommodate attachments as easily or have as many attachment options, the more narrow uprights make racking and unracking the barbell much easier which is what the rack is used for 95% of the time. Another bonus is that the attachments that are available are often cheaper than their 3x3 counterparts.
