If it's mostly magnetic, then E field might be better. If it's electric discharge (arcing, corona etc) than perhaps neither. The filtering in E field is excellent for 50-60Hz and its harmonics, so it might be better in some cases. Shielded H field might have an advantage in other situations. If you're extremely close, you may be out of luck... No, "extremely" for me might be 25meters... for you it might be 100 meters.
Keep in mind, no one can say what the influence will be. There are too many variables. It took me two months to find the one sweet spot in my garage, out of the entire dwelling, that the H field would work with good effect, consistently. Most operators have to find the best 'siting' for there systems. You will also find that the environment will change seasonally, and during different types of weather. especially if you try to operate the system for 'long distances' rather than finding that 'happy zone'... of gains, thresholds, location, etc.
