>or, in internet-speak, Your Mileage May Vary. I've read some descriptions of the Seaton-style chest that argue that it's the most efficient way to pack lots of tools in a particular space. Myself, I think it sounds maddening, having to shove tills back and forth all the time to get to the tools on the bottom or in the lower tills.
Of course, this is a fine distinction from my preference, which is mechanics' rollaways and top chests. This solution might not work in every part of the country: I'm told that in high humidity regions the metal drawers would lead to rusty tools, though I'm curious why mechanics' tools don't then get rusty (maybe they do), and though I don't find mine rusting in the damp North-Left Coast winters.
For me, though, they're marvelous - not hard to find used, so not expensive (I did pay retail for one, but another cost $20, and the seller insisted that I take the contents, which were a mixed bag of old wrenches and things), very efficient space use, and no time fussing around building them. My son laughs at me, because in an 11x11 foot shop, I've got four rollaways and three top chests - though I should mention that only one rollaway and one top chest are dedicated to woodworking tools, the others containing the tools for car repair, plumbing, electrical, metalworking, sheet metal, and general all around work.
Anyhow: I think you have to look at your space, your tool inventory, and your work preferences, and then try to sort out what will work best. It's like workbenches, though: you'll wind up having to experiment some to find a good solution. Nothing prevents you from having more than one tool storage design. I expect to make tills for my saws (which currently hang nine feet in the air, rather inconvenient), drills/braces, and drawknives.
One thing I do want to try in my currently-imaginary next (larger) shop is a little side cart on which the tools in use at the moment can sit, so they're not on the bench.
