Will one or both of these sinks be used for ntilas yadayim?
Especially on Shabbos or Yom Tov, and with lots of guests, you should consider putting at least one of the sinks as close as possible to the entrance to the kitchen. That way, if you are working in the kitchen, and people are coming in to wash, they are not in your way.
Also to consider.
Do you spend a lot of time at the sink (washing dishes, washing vegetable)? Will you feel fenced in staring at a corner?
Do you have countertop appliances that you like to leave on your counter for easy access? A corner appliance garage keeps appliances at hand, and neatly out of sight.
There are going to be many tradeoffs in whatever design you choose. Make sure your contractor gives you computer printouts of what your finished kitchen will look like. And, if you can, make cutouts – three dimensional, of your kitchen and all the cabinets and appliances. Your husband might think that you are nuts, your kids will suspect that you are just playing with arts and crafts, but it definitely will help you avoid major mistakes.
Hatzlocho Rabba!
PS. I remodeled my kitchen 18 years ago, and have been enjoying it tremendously ever since. Despite my mistakes – I did not put in a broom closet, and have regretted in since.
