I have a 5' Stanley yellow for general, Ox 30" and 24" for brickwork and rough stuff. They're just because they can be easily and cheaply replaced when they inevitably get dropped, stepped on or driven over all of which have happened at one time or another.
Then I have fat max 'I' beams in a couple of sizes which are kept clean and out of harms way for 'finishing' work.
I also have a 3' Stabila box level which is over 40 years old and has the associated knocks from use. I keep that and make sure I use it for no other reason than it was my Dad's and if it was good enough to earn his living it's good enough for me.
I have no particular preference for one make or the other, I calibrate/set them up myself so accuracy is never a worry.
