Ive always used Hansens but the pegs break and they waste space. I worked with a guy who had the Lisle magnetic trays back when they were the only game in town before magrails existed They were great and let you stack vertical in a deep tray, can take them to equipment, but I found they were expensive, so I never bought in.
I think Magrails are the answer for efficient space usage, and you can stack them, and take them to equipment, but the price is super high.
Toolgrid is cool. If I had a ton of space, Id consider it, but you cant take it to equipment and it wastes a bit space unless you go over the top with attention to detail when laying it out . Great for tool control though.
If I was still working as a mechanic daily, Id probably start investing in magrails, I think.
