Efficient and Reasonable Electriticity and Gas Supplier

Hi there,
We are a family of 4 (1 adult and 3kids), I have been using Electrabel for electricity and gas supplier for more than 5yrs. Now I would like to change and Iam tempted to have a contract with OCTA+. Would you recommend Octa+ supplier in terms of efficiency and reasonable prices?
Will appreciate your advice.
