The big4 and bigger4 are both outdated at this point. I don't recommend upgrading those at all anymore. I recommend you fill your castle with training fields (11 or 12) and 1 monster nest. You will need 3 full plots to complete the building quests, so leave at least 3 training fields at level 2 if you want to eventually complete all quests. Level 3 training fields are a huge help and are a good permanent use of gems. The guy above me pretty much nailed it on the head.
