I'm sure you've made your choice by now but for future readers, IMO it depends on two things:
1. The speed and
2. The roads.
Anything up to about 60mph is fine, fun, visceral (on a hard tail). Starting around 65/70mph is where the roads start to come into play.
DC, MD, VA have sucky roads. Specifically they aren't savvy at connecting asphalt with concrete slab which results in a "dip".
Bumps on a rigid aren't really that bad, you hit one, you go up, you come back down, you keep going.
Dips are the worst. You go downwards into the dip, then you slam into the other side of the dip going back up. My head has felt better after sparring sessions.
I'm familiar enough with where these dips are, I relax, pull back on the handlebars, and still feel the shock going up to my head. It's worse when you don't know and get caught by surprise.
That being said, the frame and rear fender look so much better on a rigid. You can't get a soft tail to look like that but if I had to do it over I'd get a soft tail.
