I think host support is easier.
Since in USB all communication is initiated by the host, the driver author gets to decide what to do and when.
For clients, you'll have to cope with whatever the host throws at you. (but to be fair: some devices are rather weird in what they answer)
But I only wrote a bunch of host drivers (ohci, uhci, ehci, some xhci stub, various class drivers) so far, and no client drivers.
