We are a pretty small enterprise(100 racks, ~300servers and lots of Cisco gear) and we are "consolidated" end of row. That means we have aggregated our switches in a few central racks and haul all of the copper to each rack.
Our datacenter is extremely nice and we pride ourselves on how the place is organized and how clean the cabling is kept. Thank being said if we were greenfield we'd probably go true top of rack because of the cabling densities in the racks are getting difficult to manage with EOR. We are looking at up to 60 copper connections per rack and at least 24 FC fiber. The EOR consolidation of copper is a massive chokepoint/headache and we'd likely not do it again:) There are dozens of technical arguments either way, but our "issue" is primarily cable density.... YMMV....
