Perk vs. Curve?

My partner and I are looking for a new dildo for strap-on use... she's ready to venture into penetrative sex, which she's never tried before. I'm looking for something small to start off with as she's extremely tight and nervous about how it's going to feel. We started off with a giant compare list and narrowed it down to the Happy Valley 'Perk' versus the Tantus 'Curve'. We've read over all the reviews but we're still curious to hear more. Anyone care to contribute? [:
