I'm just a home shop guy and I have tried the cman flat socket holder deal that takes up the entire drawer, the standard clips on a rail system, and for the last several years I have been using these magnetic holders.
What I like about them is they are easy to grab and go. The magnet is very strong and holds the sockets securely even when banged around a bit. Where they really shine is the ability to throw them under a vehicle when you know you will need some sockets for a job, and they stay organized and together in one place.
What I don't like about them is they take up a bit of room in the shallow chest drawers. This means I have three or four of the shallow drawers with just these socket set holders. The other thing that is a bit difficult is my vision is not so good anymore and my sockets are all the older type with difficult to read markings, and there are no markings on the socket places on these magnetic holders.
I've decided to maybe try a different approach. I usually keep my go-to socket sets (1/4 & 3/8 sae and metric 6pt) in the little mobile tool cart so I'll leave them in the magnetic holders since they are most likely to get used frequently and in different locations/applications. Maybe I can use a permanent marker on the plastic to put the sizes on there to help with the vision thing.
Yesterday I purchased one of the Hansen holders to try out for the remaining socket sets that live in the big roll-around/chest. This will allow me to put them in the top of the chest where they don't have to take up precious drawer space and are easy to see and access. I like that the hansen has clear size markings on the post and that the sockets are easy to lift off of the holder without much drama. However, because the sockets go open end down I can't tell from a glance whether it is a 6, 8, or 12pt set.
Oh yeah, $9.89 for the set
