Question is: what are you building? There is no general answer that will answer which is preferable. It is easy for people to come up with features they want or a customisation and they don't care for the cost of actually maintaining that feature or customisation. I work on building SaaS platform, we had multiple customers for whom we build custom features and they paid for development of those features. Not fun part is after 2-3 years those customers are gone (for example employees at customer rotated and they switched to something totally different) — but now we are left with dead feature no one is paying for supporting, some are easy to remove, some are not.
