An alternative for WP Super Cache?

haha, you have a great way with words.

Maybe it would be more helpful if you give an explanation of why you believe it is rubbish. Maybe we can help you troubleshoot your issues with the plugin.

I recommend trying out Hyper Cache

Also the combination of Hyper Cache and Cache Reloaded is recommended here.

Hope it works for you.
