Self-publishing & traditional publishing

So having gone to the conference back in October, I spontaneously decided to pitch IRON to a publisher who was there.  And they agree do publish, much to my astonishment.   They're also interested in 80AD, which is equally amazing.    
But I'm now ambiguous. Do I want the thrill of being 'traditionally' published and the simplification of all the 'stuff' that goes with that?  eg: someone else doing the tricky bits, the distribution, the editing etc.  Or do I want to have more control and try to do it all myself (retaining more of the income as well)?
I'm honestly not sure.  So I figured, while I'm waiting for the slow wheels of traditional publishing to turn, I'll try out the messier side of self-publishing with different title..  
Thus my first venture into printed self-published books begins.  CreateSpace and Ingram Spark here I come.  
Scary.
​Wish me luck
