Granted, I've only seen the last two episodes of Season 5 (season 6 hasn't been released in Australia).

But in the final episode, Rumple starts choking Hyde with his magic. And then Hyde starts bargaining for his life.

I'd say Elsa and Ingrid are formidable foes indeed. Elsa once froze an entire country by accident and Ingrid did it on purpose. And let's not forget when Ingrid was waging her war against the citizens of Storybrooke, Rumple had to bargain with her to avoid being destroyed. As he didn't try to fight her directly, that would imply he is no match for her power.

And Elsa has better control of her ice powers then Ingrid, so she'd be even more dangerous. Another point, Rumple kept Elsa's prison urn in the place where he locked away everything that was a threat to him. "Too dangerous, too unpredictable" as he put it.
