What they both said. XP is really a thing of the past and not needed. In older editions, it was important because part of the "balance" of each class was how much XP it took to level up. Fighters needed more XP per level than rogues, for example. But in 3rd edition, they normalized the XP progression for all classes, so splitting XP gained meant that, barring death, magic item creation (in 3e/3.5 crafting magic items cost XP), or level drain, everyone leveled at the same time.
4e did away with losing XP all together, and used XP as the challenge level budget, which is really what it still is in 5e.
TLDR: XP is not worth it anymore, just hand out levels as you see fit. The DMG (page 261) says that, "
[a] good rate of session-based advancement is to have characters reach 2nd level after the first session of play, 3rd level after another session, and 4th level after two more sessions. Then spend two or three sessions for each subsequent level."
