Personally i have all 3 bot DLCs, the extra reasources arent terrible and definetly make life a little easier as the game goes on.
The speed boost to the collection time is a personal preference, i like to play around with the crafting alot so it makes my life easier and im not being forced to buy extra resources, even though on occasion i do just buy it when im feeling impatient.
The personality pack is a more debateable purchase, personally i find the lil dudes to be sarcasticly hilarious, but ive viewed a few posts where the personality pack falls short for players who are expecting interactive bots, which they are not, they just speak to you when they want.
Overall id say play the game through once to establish if it has staying power for you personally, or if its falling short then decide if its worth it to spend the extra cash or if you're just going to put the game away in a month.
