I like the Lost Kingdom models, they fit my aesthetic more. But there are a lot of other great ones like Dancing Yak (more cartoony version of 4th edition style) that also have a full range of models.
For a full army, I would probably buy a resin printer and find a set of models I like:
Fabezel has a good set that are similar in style to the 4th ed models (make sure you keep clear of the guy who copied his stuff and resells it)
