Wizzley has a professional look but its ad share percentage is pretty low compared to other options. Squidoo looks too spammy and it's not a good platform for establishing yourself as a serious writer, it's just a bunch of internet marketers. So of the three options you listed, HubPages is probably the best--better earnings and less of a reputation for being a spam mill.
In my profile I have some links to other revenue sharing sites that give writers a larger share of the ad impressions, 70%-75%. These sites also allow links, so they're a good way to create more affiliate income or backlink your other articles.
