I think both are better!
For vegetables I think you can do the same with frames on which it will be super easy to add extra protection if necessary.
In the greenhouses pro of the valley they have all a system of cables and ropes to protect in the greenhouses to make the handling not too expensive.
We ... Mrs. is obliged to spread P30, it is long and not practical.
With frames you have straw scales for the night, or old blankets or anything, it takes you 30 seconds and you're painstaking.
For young shoots to grow you can start your tomatoes underneath and fold the lid when the plants have grown enough, at a time when, in general they fear nothing.
And if it sucks then you use a chassis of 40 instead of a 20cm high chassis and 40cm there for your tomatoes is on we are in June ...
Other interest protection against flying ...
You can very well consider (I consider it in future proto) to make removable the two layers of greenhouse cover of the lid BUT to keep the P30 that lets day and rain pass but will brake (or not) the pillar for example.
To be continued....
For the rest: comfort, rain, sweetness of life ... I agree and Mrs even more because even in winter it is good to work in the greenhouse.
