There is more to it than the size of the knife. Hardness, edge angle/thickness, grind...all play a part. A good big knife can offer some things that a hatchet cannot. It is not, however, the end all. As was said, it is just different.
It is much like the Rock, Paper, Scissors game kids play. For strength in one area you compromise in another. Machete gives added reach and tip speed for lighter work. Some big knives keep an edge longer and cut more efficiently than a machete, but do not have the speed for the lighter work. Some hatchets could cut wood crossgrain more efficiently, but do not limb as well, and sometimes weigh considerably more. For that matter, some jobs are better done w/ a saw.
Figure out what your needs are. If you need a machete, get one. If a big knife lets you chop small wood and split it easily, get it. Most importantly, get the right tool for the job. Just as some small knives perform fine tasks better than others, there are various large blades w/ different reasons for being and varied strengths and weaknesses. First figure out what tool you need, then find the optimal one for the job.
