There is a 3rd option here that I see some people doing, but isn’t generally talked about.
If your true goal is to “ascend” (which it is for everyone sooner or later) you can opt to reincarnate a number of times as quickly as possible. I have seen some even rein tilling and other xp skills but I definitely do not recommend in case you decide to change your mind when you see that insane refund later on.
The goal for this style is to boost your xp and myst bonus before you start grinding for your high level upgrades. It does, however, require you to have a tribe to protect you same as any other reincarnater (before the key combat carns or if you are bad at pvp)
Overall the answer to the question depends entirely on the player and the type of play experience they desire.
