Playing LH chords is easier for me. I'm practicing playing the other way because the other way sounds fuller when playing solo. Also, playing RH chords, you can turn a sheet music page without too much interruption in sound.
I think LH chords are easier for me because that's how the cat who first taught me how to play something showed me. So, I was practicing LH chords from the get go. Now, I'm working on the other method.
When playing left hand chords, it works best with a bassist and not playing the root. Or, even if playing solo, I prefer playing the LH chords toward middle C and up. Else, the full LH chord sounds muddy in the lower registers.
