have you played with the s4 in a store? if not that may help.
i have always bought htc for the hardware.i pretty typically run cm,as i dont care much for any UI that the mfgr likes to throw on. its only been recently that sense has grown on me(i think sense 4 has a certain elegance) tho admitedly im not a fan of sense 5.
