Most secure Ravencoin wallet?

I've started to mine Ravencoin recently. I received my first payout. I'm mining it directly to my core wallet. I wanted to keep it somewhere safe in a third party wallet, it is safe to store the coins in a third party wallet? If yes, what is the best wallet out there? What are the benefits?

Or should I let it be in my core wallet?

//Note: I use paper wallets for my ETH storage//
