That said it's still "cool" to hate the other clients so it doesn't surprise me when threads like this pop up.
It isn't cool to hate other clients it is just a pain in the arse to deal with other clients. It is like websites. I buy pretty much everything I buy online on one very popular website which I am sure you know the name of simply because I don't want to have to make accounts on loads of different websites even if I can get a better deal somewhere else. It is the same reason I always try and pay with PayPal if I can. I don't want loads of different websites knowing my credit card details.
