How to choose an awning??

CONFUSED NEWBIE

We are completely new to caravanning and any help would be very gratefully received.

We will be on a seasonal pitch and are looking at awnings and leaning towards the Inaca Siena (with steel poles) over the Bradcote Residencia (on looks) and an Isabella (on cost).

Any help/advice/information would be really helpful as we have no clue what we are doing and are getting too confused to make a decision.

Thanks for reading this ramble!!
