Second photographer vs more time with 1 photographer

For those who have had their wedding, do you think it’s more valuable to have a second shooter to capture more candids of you/guests during core events or pay the same amount for an extra 90 minutes of coverage by 1 photographer?

For context, that extra 90 would get coverage of our after party which we have some fun things planned for (interactive/group activities). Could have a friend designated to take some shots with a disposable. But I also really value those candids during key moments.
