[Help-bash] Are declare and typeset exactly the same? Which one is more popular among all shells?

[Peng Yu]

Hi,

man bash says the following. I assume this means that declare and
typeset are exactly the same in bash. Is it so?

       declare [-aAfFgilnrtux] [-p] [name[=value] ...]
       typeset [-aAfFgilnrtux] [-p] [name[=value] ...]

ksh only has typeset. Is typeset more popular among all the
contemporary shells than declare? Thanks.
