Short answer: the Zealot ZE41 for value, the W-King D20 if you want the microphones. The ZE41 is called the absolute best value for bass performance, play time and max volume in the boombox class, at the cost of being the heaviest and biggest boombox around. The D20 ships with two wireless microphones but has a rising response with rolled-off upper treble and 700Hz and 1.2kHz peaks.
Buy the Zealot ZE41. It is rated higher for sound quality, and the $26.95 you would save on the W-King D20 does not close the gap.
Battery life favors the W-King D20: rated for 24 hours against 4 hours for the Zealot ZE41.
