For soloing, I don't think much beats hammers. Maybe machine guns if you don't mind the brass. I suspect clubs would be competitive because it looks like they also do stuns and knockdowns and while there's no AE, they can swing faster so in theory you can bop zombies in sequence, keeping them down til you kill them all. Usually I can handle 3 green zombies at once, just by knocking them down. Easiest if I can round them up and hit them all at once. Even soldiers or the alien guys rarely give me trouble. Only time it gets dicey is if I fail too many knockbacks in a row. Add in a junk turret with some levels in it and you're hard to beat (1 junk turret at level 4 is good enough to solo most things. You can mod them a little bit too. Rad reducer and drum magazine, for sure.)

If you use shotguns, bring slugs. It's pretty quick to switch ammo types. Regular ammo is best most of the time but I've noticed high armor zombies won't get stunned by shotgun blasts and can whoop your ass while you shoot them. I think the problem is you need to pass a damage threshold and shotgun shells vs high armor won't cut it. Slugs will, though. Really you can't go wrong with slugs other than if the target is a regular low armor zombie, the regular shells do about twice as much damage.

So I mostly solo with heavy armor (70%+ damage mitigation) and a sledge hammer and right click swing unless I'm low on stamina. Junk turret if I think about it and shotgun for panic fire (though a lot of times I think I'm actually better off sticking with the hammer).
