Base game, not including mods? It’s comparable, especially if you didn’t like career mode and preferred science mode. I can see where they’re going and I really like it personally.
However, if you also include mods, and you kinda have to… the sheer quality and amount of mods that really elevate ksp1 is going to make the answer to this question “no” until it has been out for years. You simply cannot compete with a decade of overhauls, dlc sized expansion mods, and visual upgrades.
I’m trying to do space exploration and Jesus it has a hell of a curve, especially if you’re playing alone
