Question Static vs Dynamic Data Text

What is best practice for static vs dynamic text?

Say I have

resource type: value

. Should I use two TextMeshProUGUI objects? If I should use two, should I try and attach as much static text to the static (unchanging) TextMeshProUGUI as I can or is it negligible?

If I should separate static and dynamic text should it look like this?

Where the "Static Item 0" is one TextMeshProUGUI object and each numbered Dynamic Item is a separate TextMeshProUGUI?

I've heard regeneration is costly, so I figured I should at least be aware of best practices.

Thanks
