Never been, but I know some "devout" Methodists and I've been reading about the shoddy state of it for years at American Family Association. (AFA was founded - and still run - by a Methodist minister.)
My impression now is that no church is more replete w/liberal equivocation and sin than Methodists as of now.
My grandmother played the organ for our church since she was 12 years old. In 70 years she only missed a handfull of Sundays. She doesn't go to church anymore. She says God doesn't live there anymore. These days she says she finds God when she works in the garden or walks the dog.
