The main brands I would see would be Glenair, Souriau, and ITT Canon. Once you are paying the the space quality hardware, its all much of a muchness really. Glenair would probably be top dogs in this space.
I have used other manufactures with their own propriety connectors, like Harwin, which are a bit awkward.
The various styles of connectors do matter a bit. Micro-DSUB and Nano-DSUB are a bit of a pain, as you generally get the connector with flying leads, so have to inline (butt) splice.
38999 Circular connectors are great to work with the hardware, but order the right parts is a nightmare as they all have phone number part names.
