Fen Light vs. Umbrella in 2026? Which one is actually faster?

I've been using Fen Light for the past year and it's been rock solid with my Real-Debrid account. But I keep hearing people rave about Umbrella's custom scrapers finding more 4K links for older obscure movies. Has anyone done a direct speed comparison between the two lately on a low-end device like a Firestick?
