Glass, Glossy Plastic, Aluminum
You know, the iPhone 5c gets a bad rap for being the ugliest iPhone ever made next to the 3G series. But if it had a matte or rubberized plastic finish instead of glossy, I would've considered it since the face is practically the same as the iPhone 5. The battery doesn't have to be removable but if it had a swappable back cover, it could have sold alot better for customers who prefer function over flash.
Late last night, I actually did see a tiny crack on top of my LG G3 Beat. Matte plastic. Oh, well! I'm telling you, rubberized plastic material is the way to go. Bounce effect. My $30 phones came away unscathed like it never happened. Motorola and Nokia are the best! If an iPhone SE or 6s hit the tile like my LG did, I expect a crack on the top area. Metal isn't indestructible. Moto E2 is my favorite for ergonomics since the Nexus One.
^ A budget phone built to withstand falls unlike expensive glass-made Samsungs, Sonys, and my $180 LG G3 Beat and $250 Xiaomi Mi 3 couldn't do without showing any tiny cosmetic damage. Find build quality that absorbs sudden impact better like in that Nexus One vid. Bounce effect.
It isn't difficult to make a "pretty" design. It is finding a pretty design that is also comfortable to hold and durable to drops. Getting that trifecta is quite rare.

The only device that gets 9's across for me is the Nexus One. My Moto E2 has nearly 3x longer battery life than it and much quicker though. Nexus One also has a better design than the HTC Desire phones that looked like it. That design is also a bit UNIQUE-looking and didn't get played out like other slabs. Blackberry Bold 9000 almost gets the trifecta for me especially for a QWERTY. The faux leather back felt wonderful to hold. Just a bit too thick.
A good iPhone design would look like...
Front - iPhone 2G (chrome bezel)
Back - iPhone 5 series
Shape and size - iPhone 6 or Moto X
My ideal height is 130mm with a "4.5-4.7 display as seen with the Moto X (2013).
Would Apple ever make that perfect iPhone design for us? Of course not! What's the point of upgrading every few years with the perfect iPhone and battery? If it comes in metal, people complain it is chipping off or it got dented from a fall. If glass, it cracks like eggs. If plastic, they go ewww! They want that premium look and feeling. Not another 5c.
Even if Apple made the perfect iPhone inside/out, some of us will just grow bored of it eventually and yearn for something better since technology evolves with newer features every year. The perfect specs and design in 2017 might not be perfect in 2020. The glass is always half empty...
^ Again, a great "overall" design shouldn't need to be covered up by a case. Built to last and not only built to look good, dent, or scrape off...
