It's not as good as the original because it doesn't have the best routes, but if you like Arcueid's route it's better. It's just an expanded version of her route (with nrvnqsr removed).
Ciel's route is entirely new since her old route was basically the same as Arcueid's, it's a lot more like Fate and modern TM stuff than the original Tsukihime. It gets pretty nutty towards the end and there's some fun Roa stuff in it.
Red Garden should have Sachin's route as well as the maids' and Akiha's, but I expect if it ever gets done Nasu will actually split it into 3 games because if not Red Garden will be like 2x as big as the first remake which is already longer than the original game.
