Better how? Gain? F/B? Width of main lobe? Absence of side lobes?
What?
Nearly all antennas are 100% efficient at squirting out the RF, it is
just a question of what percentage of your RF goes in what direction.
Gain is not the be-all and end-all of antennas, nor is F/B ratio or
any other single parameter.
Those who lust after gain should use optimized monobanders. Those who
want maximum F/B should use a yagi with two reflectors, etc, etc, etc.
A SteppIR is a compromise on everything except tuneability, so if
tuneability and the ability to switch 180 degrees faster than you can
turn a rotator, that's your baby. For every other parameter, there is
some antenna out there - many for less money - this will beat it.
You pays your money and you takes your choice.
