Hard part about that question is that the kits reflect you music tastes. I also have those kits, and not being a rocky type person, they are probably going to cover my rock needs. I was lucky with my upgrade to AD2 to get the session kits, but have supplimented these with the dry kit an the brush kit. I reckon the dry kit is work looking at if you like a rock sound, but want something different, but not if you want something harder. The demo with the brush kit includes a folk track, which even though I like jazz made me more comfortable going for them. hearing the same kit in a different context.
There are a couple of kits that interest me, but nothing urgent. I have a some kitpeice credits on my XLN account, for when I decide what kit pieces to go for, so I think I will take the same approach with the credits I get from the platinum upgrade, just sit on them until I know more what I'm after. It will probably be Session percussion and Reel machines, leaving one more adpak Who know what XLN will do this year, maybe worth leaving a credit or two on your account in case something really interesting comes along.
