Questions about colour stamp pads

[Cavaliers]

Hi, everyone
It's been a while since I visited - but I know this is a good place to come
for information and advice from previous visits.

This time it's about colour stamp pads. I've just gotten into getting some
stamp pads - there are so many of them. I didn't realise.

Can anyone explain their different uses to me please?

So I have so far I have some Colorbox:
1. Chalk ink pad
2. Pigment brush pad
Question: what are their different uses?
Used for different papers or what?

Then I have some Tsukineko colours:
1. Versa Magic Chalk (it says: for a soft matte look versatile fast-drying)
2. Versa Color (it says: water based ultimate pigment) wow!
3. Memento (it says water based fast drying on most paper surfaces) what's
the difference between Versa Color and Memento I wonder ... ?

Questions: what is the difference between each?

And are some better on 'shiny' papers (excuse my terminology).

Thanks in advance for insights to this seemingly complicated,
