my gear, stalker set: battlemaster head (other 4 champ pieces), champion bracers, matrix cube, other is battlemaster
So. Expertise difference:
4/5 columi - 448 expertise ( 9.44%)
4/5 champion - 632 exoertise (11.87%)
it is 2.43% difference.
Endurance/Willpower armorings difference (looked in knotor.com)
4/5 columni: 184 Endurance and 200 Willpower
4/5 stalker: 116 Endurance and 120 Willpower
68 endurance difference (its 680 more hp and its better than expertise 2.43% damage reduction)
80 willpower difference (i am not into math a lot, but according my calculations that gives 1.8% total dmg, so PvP bonus dmg is like 0.6-0.65% better) It also gives ~+0.005% crit chance
And i think (no calculations tho) that 4 columni set bonus (+15% crtical chance on tharsh/voltaic slash) much better than 1 more recklessness charge, espessialy for deception.
What do u think?
