Cumbria biomass work questions

Shouldabeenajoiner:
Interested in working for either Aw Jenkinsons. Dent logistics or Stobart group. Which on is best. Im leaning towards Dent smaller company, nice variety of work/ places to see, have decent trucks and most are back by tea on a friday etc only downside is no truckstops paid laybys only.
Someone sell me the job good and bad.

Out of the 3 why would you choose the sub contractor who I would bet sure as hell pay less than the 2 direct companies.
Also Stobarts and Jenkys pay all parking, so again why choose the one who does not.
I know a lad on Stobart Biomas, and a lad on Jenkys, they too are usually home at a reasonable time Friday.
I also know a lad on Tues to Sat on Jenkys, he is always finished early Saturdays.
