>>13118078well to start, we should ask what aspects of an electron make it particle-like. these are:
1. the electron is quantized, you can't split an electron into two 1/2-electrons
2. its interactions tend to occur at single points eg in the double slit experiment, a single electron will make a single mark on the detector screen
in most other properties the electron is wave-like. furthermore, 2. is still compatible with the wave-like nature, and merely implies that gaining the knowledge of the electron's xy-position will lead to corresponding uncertainty in its momentum
so point 1 leads to quantum field theory. in this, there is a field, like the EM field, that extends throughout the universe called the electron field. electrons are waves in this field, the field's quantized nature is what makes it so you can only have discrete numbers of them and not eg half an electron.
now why do we believe in quantum field theory? it leads to great predictions in high-energy physics, like that that occurs in particle colliders. any physics treating the electron like a particle carried by a wave doesn't make these same predictions.
you may want to look into the pilot wave theory of QM, it is analogous to your suggestion, i think many treatments could show you why it has fallen out of favor.
