How about a summary of the options presented thus far?
The various inks don't stand up to solvents used to clean the sockets (as Cheese just mentioned). I use mine mainly on my car, so after a job they get a wipe down with a rag soaked with brake cleaner (I like to keep them clean). In environments where they don't get subjected to the grunge in a car, this should be a non-issue.
Laser etching does wear off with enough use. If you used your sockets daily like an auto mechanic, your most used sockets might see the labeling wear off in a year. Most sockets are roll stamped for this reason. But it's probably a non-issue for the average homeowner.
Both of the above solve the visibility issue, but don't address organization. Hunting through 30+ loose sockets that are easy to read but just tossed in a drawer gets old fast.
The socket rails can be a nice organizational tool, but don't often help with visibility with stamped sockets and can be a nuisance to grab the entire rail just to find what you need. You need to make sure you put the sockets back in the rail with the size facing the same direction or you'll drive yourself crazy the next time you're looking for a socket. Pulling the sockets off the rail can be a nuisance, each rail brand will have varying degrees tension to hold the socket (or magnetic). Try before you buy to make sure you're happy. They are very space efficient though. And if you have shallow drawers, they will still work by turning them on their sides. Deep sockets on rails will fall over anyway unless you prop them up.
The socket trays often leave empty holes for sizes you don't have (or rarely missing holes for sizes you do have), the hole widths are oversized to accommodate impact sockets and generally they aren't space efficient with the empty holes and gaps between the sockets. You also need 4" deep drawers to accommodate deep sockets standing up in these trays. More space inefficiency here. Visibility and access is great, portability less so if you're taking an entire set to your work. Rails are better here.
