I have a set of slugged plastic chips. They're very heavy (13g), hard, and slick, which are downsides. But I got them because I love the way they look.
I enjoy them. I have a lot of different sets, and I enjoy them all for different reasons.
The chips you linked to have a unique, interesting graphic design. If you really like the way they look, then by all means consider buying them. But be advised that they're almost certainly going to be heavy, hard, and slick simply because they're mass-market slugged plastic. They're also pretty expensive relative to most other mass-market slugged plastics, and the breakdown (how many chips there are of each denomination) is somewhat awkward.
Unless you're in love with the design, I'd pass. There are lots of other interesting designs to choose from on chips that are less expensive for the same quality, or much higher quality for not too much more money.
