Jupiter Albufeira is not open yet. There is a very long thread on this forum regarding the late opening and many families of holiday makers have been let down very badly. Depending on when you intend to visit I would go for somewhere other than Jupiter for this year anyway. Hopefully it will be up and running for next year.Edited: 9:28 am, June 12, 2018
The two locations could hardly be more different. Jupiter Albufeira is the former Hotel Montechoro, rebuilt and rebranded. It is in a heavily built up area a mile or so from the beach called Praia da Oura, a few steps from the main tourist bar and partying areas of town called 'the strip' and not far from anywhere else.
They are completely different types of areas and resorts, one being fairly quiet and scenic with beaches, the other being quite touristy and near to the centre of all the night life, so would think carefully and do your research before making a decision.
