Uranus and Neptune have similar mass and size. Venus and Earth are actually not as close in terms of mass. Neptune is the heavier of the two gas giants, the ratio of their masses is 0.87, while the mass ratio of Venus to Earth is only 0.82.

Which has a more powerful gravity a small planet or a large planet?
It would depend on the mass of the planets. The surface gravity of a planet is directly proportional to its mass and inversely proportional to the square of its radius. If two planets have the same mass but different sizes, the smaller planet will have stronger gravity because the surface is closer to the center of mass. Conversely, if two planets are of the same size, the one with more mass will have stronger gravity. Since larger planets usually have more mass than smaller ones they usually have stronger gravity, though not always.
