Cap amount bonus is not stacking nerfed. Cap recharge time reduction is not stacking nerfed. Also, reduced efficiency of multiple cap recharge time reducers is a common misconception.
Here's some math.
Assuming a ship with 1000 cap and 200 sec recharge time. Base recharge is 5 average, 12.5 peak.
One recharge rig: -15%
New values: 1000 cap in 170 seconds. Recharge is now 5.882 average, 14.706 peak.
5.882 / 0.05 = 117.64
This means that if you set 5 cap/sec as 100%, after the rig has been applied your cap recharge is at 117.64%.
Second recharge rig: -15% again
New values: 1000 cap in 144.5 seconds. Recharges are now 6.920 average, 17.301 peak.
6.920 / 0.05882 = 117.64
This means that if you set 5.882 cap/sec (the value with one rig) as 100%, after the second rig has been applied your cap recharge is at 117.64%.
This means: the second rig gives exactly the same increase in cap recharge as the first one. Yes, it removes less seconds from the number, but that is only because the number is smaller to start with. A repeated percentual increase or decrease will always yield in the exact same repeated benefits or drawbacks.
Now, let's compare one capacitor amount rig with one capacitor recharge rig.
+15% capacitor amount, no recharge time reducton
New values: 1150 cap in 200 seconds. Recharge times are now 5.75 average, 14.375 peak. If you look a little ways up, you will see that this is nearly identical to the benefits of a 15% recharge time reduction. However, you have the added benefit of having more cap to spend, and additionally (given a not too rapid drain on the cap) it will take much longer for your cap to 'break', i.e. fall below 33% where the recharge rate begins to decrease ("buffer factor").
Thus the capacitor amount rig is slightly superior. Not enough to justify double the build cost, but still slightly superior.
Result: you will get more peak recharge with recharge time reducers, but only a trivial amount more than with capacitor amount bonus rigs. Choose your combination as you see fit, but do not underestimate either of them. If you want to compare specific combinations you can easily use the math as demonstrated above.
