I thin if I had to choose just on what you've said I'd say the former - there just seems to be a lot less work for the same pay.
BUT, it's impossible to tell whether you'll be happy in a school or not until you've worked there a while, so the only thing you can do is go have a look round with very open eyes, talk to as many people as you can, get a feel for the management, and how easy-going the schools are.
Going for a look round doesn't always work, but I've definitely been able to cross schools off my list from looking round eg. when I was looking round one school, the deputy head admitted that they'd just got rid of the Head of English, Maths and Science (in her words "they just decided to leave, with no job to go to, but it was very convenient for us because we could get better replacements") - it was so obvious they'd been bullied out so I never applied there.
What are the commutes like? A short commute would sway it for me.
