The four synch is miles ahead stronger because the load bearing layshaft is
bigger and unlike in the three synchro, the four synchro does not expect a
small amount of metal to do twice the amount of work ie first gear and reverse
gear. Larger bearings in the four synchro.
The 4 synch seems to last forever and when it does wear out its usually only
bearings and synchro worn whereas when the three sync goes it requires the
replacement of all the major expensive gears usually.
