Does sodium hydroxide increase PH more than kalkwasser?

I dose limewater and lye (in water) separately. Clearly, the lye increases PH more than the limewater but the question is a little more complicated.

I can only so much without my alk rising over my target. So, for a given impact on alkalinity, which has a bigger impact on PH?

Thanks in advance

It's the same, per unit of Alkalinity. You don't have the evaporation limit concerns with sodium hydroxide, obviously.

That's the exact piece of information I was looking for. Thank you
