Hi temple, This is my personal experience with the txbit exchange.
It's been great so far. I haven't had any bad experiences as such.
Features i liked/observed:

• Allow for both kyc and non-kyc accounts.
• Secure email based or 2-FA based login.
• 0% trading fees for a limited time
• Nice Dashboard to see everything at one place.
• Deposits and withdrawals were quick
• With respect to x42 they have fiat pairs as well

Areas of improvement i would like to see would be Liquidity, which should gradually improve over time and also the improvement in withdrawal fee structure.
