Both ways are fundamentally different and complement each other.
Remote X-server connection (XDMCP):
Connection security: none;
furthermore the X server is exposed as a network service.
Performance: excellent (on LAN), though not all 2D/3D acceleration may
be available (not sure of the precise details).
Desktop functions: available, the whole desktop is remote.
Is sometimes not well supported because of a perceived lack of
use-case.
ssh X forwarding:
Connection security: excellent.
Performance: sucks. Bordering on being useable on a 100Mbit LAN, with
apps that contain their own operating system (like all the mozilla
stuff), or KDE apps. Perfect for straightforward X11 apps like nedit.
Desktop functions: not available; only individual apps can be run.
There's a third option:
Remote desktop:
E.g. VNC type methods.
Connection security: possible, SSL
Performance: lousy. Sluggish even on LAN, and the clients I tried
really sucked - severe graphics errors, dumb layout wasting screen
real estate, unsupported software. Badly designed protocols to top it
off (my impression).
My conclusion: useless.
