Not going to get much of a "rich" look out of any vinyl product.
If I did have to choose I'd go with the sheet goods. No seams to open up.
How long it holds up is going to be a factor of high a quality floor you buy.
I have one house where the sheet vinyl has been in place for over 20 years and still looks like new even in front of the sink and side door where there would be a wear pattern.
