Necro vs Wizzy. Which brings more to a group?

[Vallanor]

Wizards are great for soloing while getting things done around the house. Once you start quadding, you'll kill four mobs in about two minutes, then AFK med for ten minutes (do the dishes, clean the bathroom), then do it all again.

They're also great on raids. I've finally started using GamParse to see how my wizard stacks up on things like Vindi and Halls of Testing trash, and find myself in the top three dps most of the time.

If pulls happen too rapidly though, my efficiency drops pretty fast. For this reason, wizards are pretty bad in groups. On a fresh server where great ratio weapons and haste are hard to come by, wizard dps is fine in groups, but classic EQ itemization is so favorable to melee toons once these items become readily available. Stacking mana regen on a wizard doesn't have nearly the same impact as 100% haste and an uber ratio weapon on a melee toon. Clicky nukes help, but good ones aren't really attainable until level 60.

So... to answer the question, necromancer is much better in groups. They have sustained dps in the form of a pet, they can help pull with FD, they can mez, they can heal. Wizards are better left to soloing and raiding.
