The workhorse of my gym. I'll recommend getting the shrouds as it becomes another place to put magnetic hooks or bins toward, as well as the 300 pound upgrade so you will never be strong enough to outlift the machine. Attachments are great, build quality is awesome.
One issue I found and has been mentioned other places is that the HR has smaller space to put spotter arms compared to the 6 post version. You'll have to move the cable out of the way to do it. Minor inconvenience for me, but I know it can grind folks gears.
Another potential issue of the FM HR is there is little in the way of permanent side attachments you can put on the holes due to the shrouds and cable system. I have struggled to find places to put landmine attachments and other barbell holders in a way that makes the rack carry everything, but it's hard to get around the shrouds and other cable parts to make it work. I've found other solutions, but just a warning if you though you could attach everything and leave it on
I am happy with my choice at the end of the day. I got it for the all in one aspect as well as the smallest footprint without comprising on stack weight and plate storage. If you prefer or have room to hang things on a wall you might be able to pursue other options, but if you want something literally stacked this is a great way to go!
