I use the basic version of PayPal for subscriptions, but I've had issues with canceling customers' subscriptions without their explicit request, and the PayPal support is horrendous.
The fees are a little higher than some of the other services, but it integrates fine, so if you're okay with a clunky but easy to set up service, you might find it useful as well.
Unfortunately PayPal is pretty much the only option, if you're based in Europe and want to do recurring payments.
I agree with all the points above: the support is worst I've ever experienced, the user experience is horrible and hasn't improved over the years, and the recurring payments clearly don't belong to the product.
