"all the problems" are really old, old news, long ago addressed and resolved. In fact, such statements are more FUD than anything else. Certainly you MUST know that Apache httpd supports PHP-FPM, for example.
I never understand these arguments that basically pit Apache2 on its own/with modules against a completely modular arrangement of tls/cache/web/app as different layers.
If you use apache as the "web" in that setup, it needs relatively few modules loaded and when configured correctly can be blazing fast.
