Replace or Embrace Textured Walls and Ceiling?

[u/bad5190]

Nearly whole house has textured walls and ceilings. I’m not a fan. They look very dated, but so does all of the molding, lighting fixtures, closets, etc. do you think it’s really worth mudding/sanding or is it not as big of a deal to have textured walls and ceilings? Seems like it would be either a huge pain DIY or very expensive with a contractor.

Style: Swirls on most but the basement is patchy like Tuscan plaster I believe.
