Hi Janne
There are very good tools out there for this task: the Tamiya 74123 Side Cutter is intended for removing plastic parts from sprues as well as nipping on photoetched pieces. Then there's also the Gundam Planet Side Cutter, which performs exactly as the Tamiya does, only that the tips on the latter are a little more blunt, and not so pointy as the former.
I've learnt about the God's Hands and DSPIAE too, but I don't know any of them.
I use the Gundam Planet one for removing plastic from sprues and the Tamiya tool for removing photoetched parts from the frets.
Always
