What tools to use to cut blanks from full sheets

[mburtis]

After watching a couple videos I think I might be able to get my snips to actually work for trimming panels but still wondering what options work well for cutting pieces out of full sheets. Is electric shears or a nibble about the best option? Is there any sort of hand shears that can cut out of full sheets? Best option I got right now is a cut off wheel in the grinder but it's a rather unenjoyable way to go about it.
