Huge impact on fill stats?

Was wondering is there a dramatic impact between +13 and +15 stats on gear?
Some stats are hard as freak to find however there are mostly available as lower form such as s5,cd13,cd7,c13 comparing to famous stats such as s5,cd15,c15,cd7.
Just wanna know the difference honestly

 

+15 stats are better than +13 as 130 cap was 8 months ago (which is outdated). +15 stats also cost more than +13 as material cost is exponential.

 

Is there a huge impact between both?
I mean will a +13 stats arm be reasonable to use at the very least?Since the gear stats i want range from 60 to 100mill accordingly to cb where as the +13 form is slighlty cheaper ranging from 20 to 30m

 

If u use crit stat +13 crit vs +15 crit, u miss out on 2% fixed (85 vs 87).. If u can't afford +15 or want to save spina, I guess +13 is a reasonable option.

 

According to my calculation on crit rate:
Base crit rate =25
Arm with +15 =15
Weap with +15 =15
Meikyo =40
Total crit rate (base+flat cr) =25+15+15+40=95 crit rate.
Cr%= base x total cr% from equip
=25x15% = 3.75
Total crit rate =95+3.75 = 98.75
With +13
Flat +base =25+13+13+40=91
Cr%= 25x13%=3.25
Total cr =94.25
You can achieve the rest of cr from bexiz or another xtall. Decide by yourself whether its better or not to get +15 equip

 

Interesting formula,
If round off the +13 formula would be 94% vs 95%.Not much different hm.

 

94 vs. 98

Difference is 4 Crit.

Don't forget the Crit Damage you'd lose too, 4 - 6 I think.

 

Tbh the difderence isn't that huge. I'm still using +12 gears and my builds work great. Their crit rate as a few holes, but that's without using ant CRT stats. As far as damage goes, +6 cdmg, while is makes a difference, it won't be big enough of a difference to allow you to out dps everyone.
