Yes, Squidoo has a higher PR but that doesn't mean that people will read your stuff at Squidoo. For me HUbpages is a better experience and I'll stay here for my life for the appreciation I get here for writing. I've got 9 hubs here and my page views are nearly 1000 but with a single lense at Squidoo I've got 7 views so far. So my piece of advice is:
Hubpages -write whatever you want (the community here is enough for appreciation)
Squidoo -research internet, know what people love to read about and then a create lens
Bets of luck!
