In the current line, I would think KEF C3, as it's also a front ported and about the same size and similar specs.
I wouldn't buy them, even though I'm a bit of a KEF fanboy. There's a LOT of better performing speakers in that size and price range, so I encourage you to get out there and listen to some. Then buy from whoever had what you wanted and let you listen to them. It's the morally right thing to do.
My son had recently bought a pair of Q300, also a front ported speaker and I'm impressed at the sound for the money.
