Both silver and black groups can look good. Depending on the frame and the rest of the build, one may look better than the other. I don’t think silver looks best on everything and vice versa. Like the bike above. Ugly frame I agree, but the bike would look even worse with silver components.

If you want to go for a blanket statement, silver tends to look more elegant and black tends to look more sporty. Both can be beautiful.
