I was a customer of that same company that was acquired by WPengine. It had the highest ever performance benchmarks and customer approval until WPE got hold of it. I had also used WPE a couple of times earlier in its history. The service has always been bad. The business model has increasingly become squeezing the customer far beyond the point where any meaningful quality can be delivered. This year support has turned from aggressive upsells to aggressive blaming the customer for simply running the same software they've had in place for over a decade. WPE has a lot of shared hosting hidden behind its marketing cover. Classic old multitenancy problems. No one with any technical awareness and experience in WP hosting will say different. I ran into a former Flywheel tech at WCUS and heard their story of the dumpster fire that is WPE from the inside. Not surprised they fired a contributor from saying WPE as an employer discourages contributing to WordPress.
