I love my spacing of 4yrs 9months between my oldest 2. It made having a baby at home a lot easier, and despite the gap they are very close. I am about to have no 3 now but didn't do the big gap again, because the thought of dragging out the baby days any longer was quite off putting for me. So we will have a 20 month gap this time. I am worried about having 2 in care for a couple yrs, it makes me feel like I will be working solely for daycare (good thing I like my career, I guess). I just wouldn't have had it in me to get out of babyhood only to go back again - that has been the only downfall to my large gap so far.
