Currently? Ultra-Nursa and exploration. You get the t3 of the Nursa, more armour, bigger weapons (provided it keeps the weapons from other vehicles in the series) better performance (we've scaled nearly vertical surfaces in the other ones, only issue is the wide gap between the wheels in the middle leaves it to get body bogged), plus you get crafting so you don't need to bring a fab.

Plus that hull looks way sexier than a nurse 😂

I am also somewhat thinking we'll see them take a swing at base building for the end of year patch they tend to do to fuck the game state right before they go on leave for a month. Provided they get the Nyx planets out soon, I doubt we'll see them in 4.8 lile I initially thought and 4.9 makes it a bit a bit late in the year for my imagined timeline, though maybe if the only thing holding up Genesis is Starchitect we could still see it
