I undoubtedly support Planet coaster more then RCTw. Frontier were the driving force behind the RCT3 engine and I have no doubt planet coaster will be tenfold better then the current trainwreck that is/will be RCTW
PC's stuff which has been shown has looked polished. However, they haven't revealed much information and the publisher expected pre-ordering despite not telling us much and there being other alternative games out/coming out. Stupid decision that.
RCTW has shown us a lot. But, the game needs a lot of polish. However, the developers acknowledge the game isn't as good as it should be and have delayed release.
In a way, we are fortunate that we have TWO cakes to wait for. I'm just concerned that they will both end up being raisin cakes. Bare in mind how RCT3 was actually not great. It's saved by its coaster builder and moddability (and talented modding community) and its playerbase that was determined to make the game look nicer.
The next Dev Diary is out, and it's looking absolutely incredible, the game looks better than RCTW in the state that it's in now, the track editor looks good, and the whole game looks and feels like an RCT game. https://www.youtube.com/watch?v=JOAiH4_Wrc4
