HTC 8X vs. iPhone 5-Honestly...

I had my HTC 8X for about 6 Months now...problem is, I've had 5 of them. With this current 8X, I've had some really bad reboot issues and the device is extremely laggy (going into the messaging app gives my a black screen until I reboot the phone, and it gets stuck at the lock screen). Verizon supposedly dropped my insurance because I got the device from Swappa, so if anything goes wrong with it (which it looks like its on the verge of doing) I'm stuck without a phone. I didn't want to get an iPhone but AppleCare really has an advantage over a lot since you don't have to deal with a carrier that much; but I won't have to worry about constant reboots, overheating, lag, etc. I had an iPhone 4S and it was a tropper until I went to Verizon (I was on Sprint for a year), but nothing has changed that much software wise (not counting iOS 7). I'm a producer so I have to have a phone that is going to last and hold up to constant emails, texts, etc which my 8X hasn't been good at so far (outside of battery life). So, do I keep the 8X and get ANOTHER or get an i5? Thanks in advance!
