Ideal age gap to leave between children

So my wife and I just welcomed our first a few months ago, and the topic of when to have our second has come up for discussion. Relatives have commented that a gap of 2 years seems to be just the right amount of time, long enough to recover from the first pregnancy and settle into being parents, and yet close enough together that both kids can mostly participate in the same activities. I'm interested in a wider perspective from our local context though, so parents (and maybe siblings too), please share what the pros and cons of the age gap between your kids/siblings have been!
