There are advantages and disadvantages to increasing/decreasing base size. Similar to size of model having both pros and cons (easier to be seen also means easier due you to see something.)

Larger bases means a unit’s footprint is bigger. This van be bad if trying to fit lots of models into a tight spot. Larger bases means big units (especially in horde armies) might struggle to stay out of sight behind cover, or to place the unit after disembarking a vehicle, or in a deployment zone and makes it harder to get as many models into engagement range.

The same larger footprint makes it easier to get in range of objectives, and the base is part of the model so counts for line of sight, which makes it harder to hide but also easier for you to spot other models. Your units can spread out more and be more able to screen, and it is extends the range of auras if you have a larger base.

I’m sure others can give more detail and examples.
