Trunks are easier to move, but a lot harder to keep organized, especially if moved. I definitely prefer lockers because I’m a little OCD and they’re more organized.
Locker styles tend to be better if you like having small things (i.e. bits) loose yet still organized. Trunk styles are more compact but also harder to keep neat - especially little things that easily get tossed around.

In general I like lockers but trunk style is easier to transport
