Down tilt of each antenna can vary (housed inside a panel) at the sprint site, but the EVO LTE in general blows in terms of lte connectivity. Htc one is a lot better then the EVO LTE in terms of lte connectivity but does still lag behind the S3 and S4 in acquiring the lte signal. LTE signal is fragile and requires a stronger link to work, so your signal will never be as good as your 1x (unless standing or in a car close to the site)
