It depends which kind of remote access you need. For day-to-day work on my physical servers I use software access services like RDP and VNC, whereas I use VMware to access my virtual servers. When one of my servers crashes or if I want remote BIOS level access, I use my favorite KVM over IPs. - So it depends which kind of scenario/need you have....
I mostly work with HP servers and use ILO for remote management and it is really good. I came across another device which connect to all the data center products.
@whitten that device looks very interesting! We are currently using some ip kvms from Minicom which are working great, but did not know about this platform.
