Th' ol' Heart o' the Forest is the one closest to me, so I've been there both years so far. First year was a bit sparse, as she was competing with RPFN (the Casa) on every single one of her weekends.
This year, they shoved 'er back to the beginning of the summer. This made a couple o' things happen. It put her in a bit more hospitable weather (well, in comparison to 106 degrees in VacaHell, anyhow), an' it also opened the gates for merchants who couldn't make it last year. For some, having two boots in two faires simutaneously was quite an impossibility, for others, it was a new opportunity to add more weekends to the sellin' season, as it were.
That's the rosy way I see it anyhow. The Heart's a good place, smaller, a bit cozier, especially now that she's establishin' herself a bit more. There are those who would go to her instead of Casa de Faire.
And YES. You must go to Ojai at least once. ARRRRR!
