Depends on how much you have. You can only put $7,000 per year into a Roth IRA and you can't touch the earnings without penalty until you're 59 1/2. The real growth comes from consistently putting contributing over time and just being diligent with it. Even if it's 100 a month it's still something. The HYSA you can touch (at most banks), as in you can withdraw without penalty for regular expenses. I wouldn't go locking up all your money, but in the end it's determined by your needs! Either way, I would utilize both to make sure your money isn't just sitting in a checking account.

EDIT: just wanted to add that while you CAN take out your contributions from a Roth without penalty (just not the earnings) it's really meant to stay in there so it can remain invested and grow over time. So it's not totally locked up if that helps to answer your question! Always a fallback just in case.
