I personally use VirtualDub. Main reasons because it's free, has very small footprint, powerful, plenty of plugins, and you don't even have to install it, just extract the zip file and run the exe file.
I never used Pinnacle, but tried Ulead's Media Studio Pro and Adobe Premiere for DV inputs. Don't use any of these anymore, not even for DV...am using this instead to transfer full length captures and edit it with Vdub. Love Vdub!!!
