I've never been to Rolling Gate so can't comment on that.
Slipstones is fantastic, the rock is perfect, takes very little drainage (despite it's moor edge location), is very exposed so dries quickly if there's a breeze. Sometimes the rain blows clear over the top and you can climb all day in showers.
About half of the lines are worth taking a rope for. Some landings are iffy without a pad though they drain well so it shouldn't be swampy.
A word of caution, your profile shows HS as your best onsight, if that's up to date you might find Slipstones a tiny bit limited as it's generally quite fierce and crimpy. That said, there's plenty of good <VS stuff there.
It's a top crag, I'm sure you'll enjoy it.
