Aspergia would be about 25% larger than Earth, with a thicker, more humid atmosphere, as it would be 80% water. You would have all ecosystems, but it would be warmer overall than Earth. The tallest mountain would be a lofty 37,000 feet high! Rainforests would be common, with some prairie, and small desert islands.
Lifeforms would be generally more intelligent as well, with some being incredibly dangerous. Most others, though, will not be very dangerous.
Everyone gets to populate Aspergia with one lifeform of their own creation. Mine is the Aspergian Raptor, seven feet long and three feet high at the hip, its slightly larger version of a Velociraptor. When domesticated, the iridescent feathered bipeds are steadfast companions, but in the wild, they're lethal predators. Living in packs of up to fifty, they're faster smarter, & far more dangerous than lions.
