While getting the items to complete the collection, you are also generating about 4700 simoleons, meaning you could get your 10k in about 30 minutes. That besides the 10 lps and 13k~ experience from the 2 completed collections.

Also, you get simoleons, experience, town vallue and finally, one lp from leveling each sim's cooking to 6/6. Having 10 sims doing that and reset to 1/6 cooking right after they get to 6/6 by starting another hobby for 10 minutes (ie fashin design or diving), will grant you sweet rewards.

If you had doubts about this, just try it.
