I went for Chillis as my last pair were great. I got a pair of the older version of these from the clearance just as they changed the design, which fit beautifully but had a problem with a seam coming adrift two climbing sessions in. GoOutdoors sorted out to send them back for repair and the eventual resolution was that I got a pair of the new design.
These haven't had that problem, but they do seem to have downsized by about a half size. I kept going with them, in the assumption that they would stretch, but at the stage now where they're worn to the point of starting going through at the toe and there's no real sign of stretching. So, get a half size bigger than you need would be my advice, don't assume they'll be the same size as your old-style Chillis or stretch the same.
I swapped from laces with my last pair to velcro with this pair, and having three velcro straps made these as comfortable and adjustable as my old lace-ups, with the added advantage of being easy to take off if I'm stood belaying for a while :-)
