An implant is a much more invasive surgical solution. Significantly more expensive too, with bone reconstruction it can cost over 4k in Switzerland for one tooth.

If a crown is feasible, i.e. the root is ok, then just go for a crown. It can last a very long time.

What I've personally been wary of are the so called bridge-crowns, where they file nearby healthy teeth to put in a larger crown. In cases such as this, I'd go for an implant.
