I have no opinion: I don't know either engine.
I'm kinda with Herve, don't know anything about those choices. If they have at least the power of a DA100L you will be happy. DA120 will be off the optimal choice, I flew mine last year with a DLE120 just to get the prototype running quickly. It has a little more power than a DLE111 / DA100L and was lots of fun.
