Is more frequent game updates really better?

Continuous game updates mean the developers are still working hard to maintain content, which is obviously a good thing for players. However, if every update requires adapting to new gameplay, cultivating new characters, or even having your existing gear quickly become obsolete, it can be exhausting. Sometimes, rather than constantly releasing new content, I feel it's more important to fix existing issues. Do you prefer games to constantly release new content, or to first improve the existing game experience?
