Does it still matter when selecting backlinks.

It would be best if both of them were...

Before anything else i will take note of relevance rather than DR or DA it would be more practical to use a site with lesser metrics but highly relevant to the niche than one with high metrics yet not relevant the metrics serve the purpose of comparisons only.

I'd still look at DR/DA, but I wouldn't make them the main deciding factor. A relevant site in your niche with real traffic an a natural link can be much more valuable than a high-DR site that has nothing to do with your industry. Relevance + quality + real traffic should come first, metrics are more like to filter.
