Formal Shoes

Looking for input on formal shoes for black tie. There is a lot of contradictory information i’ve found, without considering the “opera slippers” option; both of the below styles of shoe is recommended by various shoe companies for formal wear, when I look further on the blogs I find disagreement on this.

Any opinions on either of these from this forum? Thanks.
