Looks like it's only Fatal 3 that different. Everytime I got that, the gear's name turned to green. I wonder if there is actually no Fatal 3, but Cri+3, and go straight to Fatal 4 (never got one tho)
Really not worth time enchanting those gears. All enchant I got is so over the place. One time I got Fatal 1/EA 2/Spell 1, other time got STR+2/AD1/INT+2
