With mine, there's usually a couple weeks difference. DS started crawling about a month ago. DD is just starting to crawl. I know it's all within normal.
Same with starting solids (purees), we both tried giving them purees. DS loved it. DD didn't like it until 2-3 weeks later and maybe didn't like the cereal like DS does.

DD hit all her physical milestones first, but DS wasn't far behind. He started rolling the day after her, but it was a few weeks after her that he started sitting on his own and crawling. He was a full month behind her for walking, but she was a very early walker.
DS was an earlier talker, but once DD started talking she never stopped and now she speaks in more complete sentences than him. At 2, DS also has better gross motor skills (he can jump with two feet, and DD cannot; he is better at kicking, throwing, catching, and hitting a ball than her). She is stronger with fine motor skills (she holds a crayon correctly 90% of the time).
They've both been within the normal timeframe for milestones, but definitely do their own thing when they're ready! My sister has twins too - her son has hit most of his milestones before her daughter. She was a very late crawler and walker, but at 18 months you'd never know that they were worried because she's pretty much caught up (she started crawling at 12 months, but then walked a month or so later).

@twodoghouse: thanks! That's so incredibly helpful to hear about your twins and your sister's!
