I’m not a professional, so these are just my thoughts. Moreover, each pro has its own preferences and needs.
If you take 1month to learn RT and you like to be in control contrast, artifacts, sharpness, and to certain degree, fidelity of colors, then you won’t go back to LR.
If you need a workflow with a couple of sliders to have the job done, then RT will struggle to be your dream raw processor.
Do you want to be in control of the end result of your images? Go for RT. Otherwise, let LR do hidden procesings for you…
