My personal choice: I run WP Engine for all 4 of my sites. The performance difference between WP Engine and Kinsta is real but marginal at typical affiliate site traffic levels. The price difference is not marginal — WP Engine's Growth plan ($45/mo, 5 sites) vs Kinsta's Business plan ($115/mo, 5 sites) is a $840/year gap.
