just take a look at the SWR curves of each antenna, and you will see

CAUTION -- SWR is NOT a measure of antenna performance. GAIN and the
overall pattern ARE. SWR tells us nothing about either. An unterminated
1,000 ft spool of RG58 will read 1.1:1 on 40M. :)
I'm not suggesting that the JK antenna isn't better, but SWR ONLY tells
us about SWR, and whether matching is needed to keep the power amp or
output stage happy enough that it will drive it to full power. That's
certainly a good thing, but it doesn't tell us how well the antenna works.
