Its all depends on you. Its depends on which crypto you are holding. But above all I always think if you are able to buy a hardware wallet then nothing better than that. But if you are on software then you can pick which device you use. If you are in mobile then go for any multiwallet like eidoo  or imtoken  or tokenpocket. Or if you are on computer then their is lots of option. But I am not so sure about web wallets I never liked that. But If you can manage more than one wallet then I will always suggest you to use official wallets. After hardware wallets,  official wallets  are most secure for me.
