I did the math on this a few days ago. If you add up the stats from full Berserker's armor + weapons, and compare that to a full set of ruby jewelry, the set of jewelry has less stats all around. I then made a full set of exotic Berserker's armor and weapons.
Full set of Berserker's Emblazoned armor:
+16% crit damage, +315 power, +224 precision
Add two weapons or a 2-hand weapon:
+10% crit damage, +180 power, +128 precision
for a total of:
+26% crit damage, +495 power, +352 precision
This is what you get for all 5 jewelry (ruby):
+17% crit damage, +336 power, +240 precision
The weapons + armor wins against the jewelry.
Now I am in the mud on deciding what jewelry to take. Maybe I'll make a full set of emerald for toughness, precision and power.
