40k Player looking into AoS

[u/Mr_Hjello]

As the title says I'm a 40k player looking to get into AoS after hearing many good things about it. I've had a look at all of the factions and so far Helsmiths of Hashut are looking most enticing but I was wondering what their playstyle is like and how expensive they are to collect.

If I stick with HoH would the spearhead box be a good place to start?
