I moved to a 735 from an 820. Screen is better albeit no glance. Performance is better. Real life usage for me has revealed less resuming, loading when switching between apps. I don't game much but have not noticed any real improvement in loading times for graphic heavy games. FFC is excellent, rear camera is also very good but beware no camera button. Battery life is phenomenal. With the same usage I get over 2 days from my 735 compared to around 16 hours with my 820. It's also a lot lighter. In summary my experience has been a lighter, snappier phone with a far better screen and enhanced features (sensorcore etc) all for ?149. Stunning value. No regrets at all about moving on.
