That assessment, though, is based on an assumption that Swedish authorities would have complied with Swedish law. Part of Assanges fear of going to Sweden, whether justified or not, is presumably that Sweden had a history of letting Swedish police get away with blatantly violating Swedish law in support of US rendition. One could argue that this risk is not real in his case, but that is/was not relevant to whether or not it affected Assange's concern about which country seemed safer.
Part of that fear was presumably based in the unusual persistence of the Swedish prosecutor, which implied something odd was going on. But that "something odd" might simply have been the prosecutors ambitions.
In any case, UK courts have a history of taking extradition hearings very seriously, and there are ample opportunities to appeal both to UK courts, the ECHR, and (for the time being) to the ECJ, so it'd by no means be easy to get him from the UK direct.
