Even if insects are unlikely to be sentient, assuming marginally decreasing sentience with neuron count and nonzero probability of insect sentience imply that eating bigger animals is probably better.
The conditions of insects in insects farming are pretty bad.
Tomasik 2019, Tomasik 2017a and Tomasik 2017b argue against this:

Eating plants is usually more efficient.
