Class Examination

White (Store bought) weapons (0 ~ 0) vs. divine weapons ( +x ~ +x).

Stat Berserker : Axes (+14 MinAtk ~ +25 MaxAtk) // Swords (+10 MinAtk ~ +17 MaxAtk)
Skill Berserker: Axes (+13 MinAtk ~ +23 MaxAtk) // Swords (+10 MinAtk ~ +17 MaxAtk)

Stat D.Knight : Swords (+4 MinAtk ~ +8 MaxAtk) // Spears (+5 MinAtk ~ +9 MaxAtk)
Skill D.Knight: Swords (+4 MinAtk ~ +7 MaxAtk) // Spears (+5 MinAtk ~ +8 MaxAtk)

Stat Valkyrie : XBows (+3 MinAtk ~ +6 MaxAtk) // Cannon (+12 MinAtk ~ +24 MaxAtk)
Skill Valkyrie: XBows (+2 MinAtk ~ +5 MaxAtk) // Cannon (+12 MinAtk ~ +24 MaxAtk)

For Elementalists, the increase of attack power is not linear, but their divines obviously outperform their white weapons.

Comparison

Comparing B Rank +7 Attack Power to E Rank divine weapons.

At D Rank Bonus go for +3 Attack Power.
At C Rank, Attack Speed +3 is good but any bonus can fit here depending on your need.
At B Rank, aim again for Attack Power, this time it'll be +4.

Now your white weapon is B Ranked; +7 Attack Power.

Berserkers
Divines will always have a greater attack power than a B ranked store bought weapon. Always use divines.

Dragon Knight
Ranking up to B with +7 Attack Power can be better. For Combats/Dragonics with Swords, you'll gain 3 more
min damage than divines and have the same max damage. For the others, you will always 2~3 min damage
but lose 1~2 max damage. It's your decision. Remember you have a C Rank bonus aswell. In my opinion,
ranking up is a wiser decision.

Valkyries
Ranking up to B with +7 Attack Power is better for crossbows. Ether cannon, divines are clearly better.

Conclusion

Which is better?

Depending on your class and style, ranking up can be better but can also require a lot of patience and Heim.
If you're going to rank up, make sure you compare your budget with the cost of divines.

Things to keep in mind;

Many of the divines in game are already +7/+8 from wonder boxes. If you decide to rank up a store bought
weapon, you'll still have to put money into enchanting to outperform the +7/+8 divines out there.

You would normally need to buy/find 8 E-Rank weapons to get a B Rank. You'll be lucky to get +7 Attack Power
in only 7 E-Rank ups. Realistically, it could take 20+ attempts to get the stats you want.
