I have Xperia XA and wanted to change to htc. Need opinions

I have Xperia XA like months ago and I have some issues with it as the battery and fluidity of OS and thinking of changing to desire eye or desire 826, 628, 630. My needs are an elegant design, sharp camera, great not laggy CPU and Great battery life. Still thinking of keeping my Xperia XA for it's elegant design.
