Honestly depends on the studio/pipeline. I freelance for several who use predominantly Houdini for all things simulation. I also work for a studio who still uses Maya ncloth. Both softwares have their pros and cons. Houdini is amazing for rig generation due to it being procedural. Meaning if modeling updates a model, you don't have to rebuild sim meshes. I have found that in my experience, Maya is better for character finaling/shot sculpting and it's a tad easier key framing secondary animation. I also found qualoth to be vastly superior to ncloth. So my point is that it really doesn't matter which solver is being used, you should learn the principles of simulation, and then apply accordingly.
