Ensure is cheaper, but it's not a full-fledged meal replacement product. It's intended to be a supplemental product to an otherwise normal diet.

"Ensure" is a whole line of different products with different roles. Ensure Complete seems to be at least as much of a meal replacement as Soylent.

I fed my brother Ensure through a tube in his nose for 2 months before an intestinal surgery. The doctors considered it as good of a meal replacement as any for that amount of time.
