One second of hovering costs 9.81 m/s of delta v.

If your aim is to achieve orbit with a reusable rocket and a reasonable
payload, you need to save as much delta v as possible.

If you aim is to ferry up tourists for a few minutes of zero g, you
don't need to economize as much.

Both choices are reasonable for what the respective companies want to
do.
