Wattvision seems closest to me. Their component count is low, their value prop is high, cost of sales has to be minimal, so they just need to get volume up (buy, buy, buy!) and any extraneous costs removed. They can beat the competition just on simplicity.

$50 would be a no-brainer.
Over $200, however, means I'll wait.
BlueLine has the non-connected version (meter connection and display) for $99. But this is only part of the equation, and they have been beating that horse for many years. The new WiFi connected device is OK, but brings the price up to parity with Wattvision, with far more components, and complexity.
