The WAGO style connectors do a pretty nice job in industrial environments but need additional wire management as part of the installation. Screw terminals don't require wire management but do benefit from this added step.
I installed control wiring inside our transmitter more than ten years ago. The transmitter was supplied with these compression type contacts. What I didn't like on those was the need to have a special tool made just for those terminals. We used #22 for most and up to #16 for the higher current requirements as specified by the manufacturer. All was stranded wire. I would guess that I wired somewhere in the neighborhood of 100 connectors over seven racks. Most of them had 10 to 20 contacts. The control cabinet has a panel that pretty much fills the rack. There has not been one failed connection. While the transmitter is firmly attached to the floor, we are on the 100th floor of Sears Tower. The building moves, a lot, and we are running cooling water through the final amplifier cabinet at 25 gallons per minute. There is not as much vibration as on ship but there is as much as an industrial installation in a factory.
