Pros/Cons to age gap between children?

We’re thinking about starting the TTC journey for #2. Our daughter is a year and 5 months old right now. We plan to start trying in February when she’ll be a year and 7 months. If we get lucky and conceive within 2 months they’ll be about 3 years apart. What is the age gap of your children and what do you see as a pro and a con? I’m still a bit on the fence and just wanted to see what your experience is with the varying age gaps.
