It so simple the best wallet to store your bitcoins so you can start transacting on the network is full node wallet. It is easy to install it on Windows PC, Apple and Linux 
Full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes. 

 I would disagree here. 

Best wallet it’s one that’s not connected to the internet at all. Full nodes need to be connected to the internet, making it very prompt to cyber security risks. 

Best thing to do with anything you want to keep safe is never ever make it touch anything that is connected to the web.
