Pros & Cons of larger advances

A couple of weeks ago, I got approached by Ulverscroft, Tantor Media and Podium - all interested in audiobook rights.

They all offered similar terms - 25% royalty, four figure advance.

Then, on the advice of a friend, I approached Spotify to see if they were interested. They offered similar terms, but a 5 figure advance. There would be a 5 figure advance for three books in the series (I’m currently working on the rough draft of book 2.)

@Thomas Umstattd Jr. I’m curious - are there any pros and cons for choosing a larger advance? I understand I don’t get any further royalties till the advance is paid out, however are there other factors I should be aware of?
