Given a sufficient count of path options, they're not really alternatives, but you need both. Like you can't do add-path <max>, as the clients won't scale. And you probably don't want only ORR, because of the convergence cost of clients not having a backup option or the lack of ECMP opportunity.
I found that if you run 6 or more paths on an RR client, the need for ORR was negated.
But yes, it does put a lot of pressure on the RE, with a 64GB RAM system being the recommended minimum, I would say.
