I use the Lee case length gauges and trimmers with a powder drill for most trimming operations. They are quick and consistent and they don't take up a lot of storage space.
I have the Lyman universal trimmer and only use it when making special cases, like 32 WSL or 7.5×54.5 for the Schmidt-Rubin. I don't think I would use the Lyman universal for day to day trimming like for, say, 223. I just think it would be too tedious for a lot of that. Setting up the depth of cut can also be a bit tedious, especially if you forget to keep a properly trimmed case as a gauge for setting the depth. Keep a case to use as a gauge and you should be good.
The Lyman universal works well. I have the power adapter for it for when I have a lot of stuff to get through. The normal cutters are holding up fine; I don't think I need the carbide cutters. I might pick them up if I saw them at a good price, though.
The set of pilots that come with the thing have worked for everything I've used them on. I've not had to buy pilots.
For deburring, I use both the little Lee chamfer tools and the Lyman case prep tool thing, depending on the thickness of the brass:

For thin brass, like the 32-20 cases I used to make 32 WSL and 1882 Swiss Ordnance pistol cases, I prefer the Lee chamfer tool.
A local shop carries the Little Crow cutters. I might try one in 223.
