Yup... Personally, Qt/Windows wallets would be the best option for now while we wait for the staking feature of the online wallet to be activated...

It's always a good practice for one to have his coins at his disposal specially if no plan in selling it yet 

They will enable the staking on the online wallet of PSB soon so just wait for further announcement. Or you can keep your PSB on your desktop or laptop so you can start staking.
