Manfrotto quick release systems, I am an absoulute fan of them. You can allways put the the camera with one hand onto the tripod and the plate will snap in and be locked on the tripod securly. No fidling around with two hands and tightening a screw and not being quite sure if the camera is now secure on the tripod like the Arca system. This is especially nice with the 234RC monpod head, with the left you hold the monopod, with the right you put your gear onto it. Done! Yes, of course I own two different quick release systems from one manufacturer. I can deal with that.
me too. I prefer RC4 because the very large plate size means much more solid contact with the camera body, and I love how i can mount the thing just by snapping it down on the spring loaded QR receiver.
My current main tripod has arca-swiss style, but I have at least a few times not noticed that the knob style QR lock had come ever so slightly loose and almost released the camera to the ground. This could never happen with the Manfrotto RC4 style which i prefer.
thus when shopping for a good "forever" tripod/head, i support trying everything you can (borrow, buy/return, etc) under actual field conditions in order to find those little quirks that interfere with your photography. It has taken me 10 years to get there, so i know it is not easy.

also, around here a tripod for sale with no QR plate could mean stolen.
same as someone selling a camera(with 1 lens mounted) and does not have the battery charger. why not? stolen.
