My BRB is much easier to deal with than my GTP. My BRB is never fussy and never huffs, puffs, or gives a hiss. He is super easy going.
My GTP is usually a good boy and during the day I can pull him out whenever I please. However if he is in a shed he needs to be left alone. Also as soon as it gets dark anything that goes near his door is a target and anything that goes inside gets bit.
As far as husbandry I do not find either that difficult but both are much more involved than a BP.
My current GTP is my second. The first was a Biak and no matter what was in a bad mood. My current is an Aru and is much more agreeable to handle. He has plenty of blue and if that is something you want you may do as I did and find a sub adult or adult to buy. That way you know their attitude too.
As for a cage a male does well in a two foot cube but many people prefer to give females a bit more room.
This book is a great read to learn more about them.
