There are several dailies systems available to you that can handle DPX as an input and create native MXF/DNxHD at the back end. In a low budget scenario where an editor or an assistant are doing the dailies - then a fully functional system like Resolve is a God-send - especially for free! Each of these systems have their own small advantages and disadvantages, but for the 80/20 rule of making dailies - they are all pretty close. I find the differences to be how much metadata logging you choose to do in dailies, as well as handling of audio, sync and its metadata.
The bigger question is understanding the difference between LUT dailies and LUT + color corrected dailies as they are not the same. I've done both for clients and they notice the difference.
I would recommend syncing in Media Composer - I think it still offers the best syncing, resync and metadata support compared to any of the dailies systems, but this all depends on the requirements of editorial.
Dailies can mean a lot of things to different people - just make sure you have all the requirements in place when creating them.
