Best handle bars for touring bike?

I’m in the process of building a touring bike and was wondering what suggestions you might have? I’m looking for comfort above everything else. I’ll use it to commute to work (about 10-15 miles each way depending on the route I take) and would like to use it for some overnight touring/camping trips that would involve riding several hours per day for maybe three days or so. Thanks in advance for the suggestions!

P.S. I’m pretty much just getting started so any other suggestions on saddle bags, etc. would also be appreciated.
