SSD is worse because when it dies you can't recover anything from it, and it dies without notice.
HDD has the information stored on physical discs that can even be dismantled, there are data recovery companies that specialize in this.
So we're not talking about speed here to recommend SSD, OP has other problems.
I lost an HDD 15 years ago, didn't have much on it but my music collection, but it was a waking call because now I do my main work on the primary SSD and I backup on a secondary HDD, ocassionaly also backing up everything important on an external drive and in cloud.
So yeah, backup is the keyword.
