I've got the original Swift (emergency, cheap replacement for dead HTC One M8) and really rate it - reliable, comfortable, and am loving Cyanogen (first time I've used non-stock Android on a phone). Also, my track record of cracking screens made the cheap replacement option appealing, though weirdly (for me) I've yet to use it as it's a tough little bugger.
Only minor gripe is the camera doesn't perform too well if light isn't spot on, but it cost me just over £100 (when they had the cashback offer) and has been otherwise faultless - it just works.
Contract with Voda about to come to an end, so heading SIM only and planning on putting some of the (significant!) savings away for eventual replacement - this looks a strong contender.
