Don't know what you mean by dramatic? If you mean, "Does Jupiter or
Saturn have as dramatic a size increase or brightness increase at
opposition as Mars does?, the answer is no. Such things are determined
by the relative distance differences when the planet is far away as
opposed to when it's nearest to Earth.

For Mars, this is considerable, because Mars' orbit is closer to Earth
than either Jupiter or Saturn.

Very good,you are on the right track


Jupiter and Saturn do look fainter and
smaller when they're near the Sun as opposed to when they're at
opposition, but the differences are minor compared to Mars.

Then you jump the tracks and lapse into geocentricity in speaking of
Jupiter and Saturn being fainter in luminosity when 'near' the Sun.

No, you misinterpreted my statements. We're amateur astronomers, so most things are expressed as how they appear in the sky, as in "Near the Sun" meaning when either planet is visible in the sky NEAR THE SUN.
