I know all these areas really well. I would say that given all you've said Hatfield Peverel would be absolutely ideal.
It's well placed for quick easy access to the A12, which for your DH to get to work is essential. don't under-estimate how much time it will take him along windy country lanes getting from some far-flung village to the A12.
It is quite large and well connected but it really does have a nice village feel to it, lots of cute period properties, wide tree lined streets, lots of open spaces, and some very nice, more modern but small 'executive' estates. There is proper countryside right on your doorstep so although it's near the A12 it does feel like green and pleasant land. There is everything you need on a daily basis in the village, a farm shop, an excellent CO-OP, dentist, Indian takeaway, fish and chip shop, hairdressers, chemist, and a brilliant well respected restaurant.
The school is good, and there are a couple of great nurseries close to the school which is really handy. It's a community school (I think) so if you live in catchment they have to take you, but I might be wrong on that - best check.
The doctors is good, there's a mainline station there, a nice clean, safe park, it's handy for Chelmsford or Colchester for the 'big' shops and it's only a short drive to Witham or Maldon for a wider selection of shops in a nice Market Town environment., The people are friendly, and it is not rough.
You have several big supermarkets to choose from, Witham has Morrisons and Tesco, Maldon has Tesco, Springfield/Boreham (near to Chelmsford) has Sainsburys and Asda. There is an Aldi somewhere too, but I can't remember where. 
Not too far if you want the beach, and near to the gorgeous Papermill Lock for lovely walks, plenty of nice gastropubs in the posher surrounding villages.
I lived there for 8 years and I was very happy there. It's not the most obviously appealing place compared to somewhere like Danbury or Little Baddow but it is affordable, and a great, practical, safe and attractive place to live.
