My first Ts were a G. pulchripes (Chaco golden knee) and a T. albopilosus (curly hair). I think both make excellent first tarantulas. Super hardy, and generally pretty docile (they may kick hair, but neither species is known for being overly quick or bolty). G. pulchripes also have some of the least irritating urticating hairs, which was a big selling point for me.
If you prefer something arboreal, anything from the Caribena or Avicularia genus could be a good choice, and there’s some truly stunning colour options.
