Display and Processor
Sony high end smartphone displays have often been underwhelming. Sony has consistently improved its display technology and the Xperia Z3+ display finally has the wow factor a flagship deserves. However, Samsung Galaxy S6’s QHD super AMOLED panel is better cashing in on the benefits of AMOLED technology like dark blacks and high contrast while drastically reducing its limitations by offering great sunlight visibility and whites. Xperia Z3+ still has better outdoor visibility. Samsung ditched Snapdragon 810 for its own Exynos 7420 with similar configuration, but based on more power efficient 14nm process technology. Despite all criticism, Sony has adopted Snapdragon 810 octa core in Xperia Z3 plus. Basic and moderate users will get great performance from both devices, but Galaxy S6 has more horsepower. Both phones have 3 GB RAM.
Camera and Internal Storage
Samsung Galaxy S6 has a 16 MP rear camera and a 5 MP front camera for selfies, while Xperia Z3+ includes a 20.7 MP rear camera and a 5.1 MP front camera. Both smartphones offer very good camera performance. Sony Xperia E3+ offers 32 GB internals storage along with 128 GB microSD support. Samsung Galaxy S6 on the other hand offers 32 GB, 64 GB and 128 GB storage variants without provision for any further expansion.

Both smartphones support rapid charging and have battery saver mode. Both batteries are non removable and E3 plus will definitely benefit from better capacity. Besides Xperia Z3+ additionally benefits from two speakers on top and bottom, MHL 3.0 and waterproof design.
Conclusion
Sony Xperia E3+ and Samsung Galaxy S6 are both high end smartphones and quite premium, but Samsung’s innovative overhaul has paid off and the new Galaxy S6 feels so much fresher.
