FBTC or FETH?

I have decided that self custody is not for me. I moved all of my coins and sold them all on an exchange. It was stressful waiting for the confirmations and for coins to transfer. It was also stressful transferring the USD back to my bank account because I don't trust the exchanges.

My plan is to buy either FBTC or FETH each paycheck. I trust Fidelity more than any crypto exchange and it will make taxes, beneficiaries etc a whole lot easier.

Would you choose FBTC or FETH for the long term? I'll be putting in about $100 every two weeks.
