The current agreements give you the freedom to renegotiate should the need arise. You can't do that when you have full membership.

In either case, changing the relationship with the EU will require negotiation, with the EU in a position of strength due, among other reasons, to the size of the single market and the awful BATNA virtually ensured by the guillotine clauses. However, full EU members looking to leave have a better negotiating position than Switzerland or EEA members.
EEA or EU members can leave any time. But when you leave, you lose access to the single market, and your economy will take a nosedive. If you're not willing to pay the price to leave the single market, you're going to have to follow EU directives and regulations. If you're going to have to follow EU directives and regulations anyway, isn't it better to at least have some say in those promulgations and insist on full EU membership?
