Well, IMO it tastes like nothing, and I'm not crazy about the texture. Anywhere that French's can be used, the mittelsharf in the pic you quoted would taste way better. It's got a bit of heat (hence the 'sharf'), but it's not burn-your-face-off hot, and is very flavourful as well. The bayerisch-suss on the far right is a nice, sweet mustard that is great with spicy sausage, and would go well on a hot dog if one isn't in the mood for heat.
I'm not even going to discuss bologna. No offence to you or other bologna lovers, but even when I ate meat I never particularly liked it.
