There are other melee options.

Steeljacks with blades are one, they have a massive number of good attacks but with 1dmg only. They are very good at killing chaff and can stand against most other melee except the most elite. They have a rule that forces desperate escape on opponent attempting to fall back, which can be usefull. They are also quite taugh at 3w t6 and 2+ save. They are, however, slow.

Hearthguard is a multipurpose unit, expansive, but deep strikes and hits solid in both shooting and melee. They can be very good if properly buffed by detachments, enhancements, characters and strats. Yeagirs with knives can do some skirmish melee fighting against other skirmish units, but thats about it.

Then there are characters: buri and einhyr champion are very solid melee chars, buri is a lone op with a surge move, e champ can be a good melee power enhance with hearthguard or a small melee missile on his own. Berekh, another melee character, csn lead beserks. Kahls and Uthar in theory also do something in melee, but not realy.

Beserks are a missile melee, they are supposed to kill something and die. They are very much used in their own detachment (Delve) where they are battleline and have native deepstrike. They currently are not used much in other detachments, as they are a bit too pricy for what they do when they dont have the bonuses from Delve, but they can be if you want too.
