So it depends on how much money you have. If you want to store an amount you can loose (like cash in your pocket) then I would go with a custodial wallet (papaybot or lobstr).
If you are more concerned about money go with a non custodial wallet - but be aware if you loose your password or keyphrase you lose your money.
And finally hard core people often use a hardware wallet.
Good luck and welcome to Stellar!
