I agree with lisap. I think the gathered neck knit top in particular doesn't read that well. The other top I would call "drape neck" rather than a true cowl, though that may be splitting hairs or I may just be wrong. For that I'd look at the fit of the top overall, sleeves, fabric, length and if it is fluid and just super flattering then that could be very useful rather than sacrificing flattering fit for a a new top just to be new. Drape neck tops can work especially well at looking elegant on certain body shapes and for more dressy tops.
Sometimes it is so item-specific due to the little tweaks over time
