your keyboard, your choice. but don't disregard the fact that most people would have been typing on dcs for at least a year or two and those on ergodox round 2/dsa retro had been using dsa for around 5 days to a month, tops?
I preferred dcs at first, having done the main area cherry profile, side buttons - dsa thing at first. But given some time with full dsa, I've since come to the conclusion that the profile (doesn't matter to me at least) in less than a week.
Besides, if you use formats like colemak and want a labelled layout without printing a custom set with wasdkeyboards, dsa is your best bet.
