i got the spigen slim armor, spigen ultra fit, incipio dualpro and the caseology drop protection cases.
spigen slim armor: this is the one i'm using right now. for a dual layer case, it adds minimal bulk. but it's not a "slim fit" case like the ultra fit or an incipio feather. it still lets me use the device with one hand though. i got the electric blue and i think it looks fantastic. it feels pretty good too. the back is a nice polished hard plastic shell while not super grippy, it never feels like the phone is going to slip out of my hand. the one thing is that i do feel that the back cover is going to attract scratches. i already have a SLIGHT scratch from when i was spinning my phone on a table at a bar. oh i almost forgot, one thing i REALLY liked about the case is that there is a lil piece that separates the camera lens and the volume button. small detail but the only case out of the bunch with this feature.
incipio dualpro: this is a great case. i think the materials feel better than their spigen slim armor counterpart. it adds slightly more bulk than the slim armor. if you can barely use the phone with one hand now, i would not recommend this case. the back is a hard rubber and it feels great while adding a solid amount of grip. the material seems like it'd be more resistant to scratches than the polished plastic back of the slim armor. my case didn't fit EXACTLY perfect.. the back bottom part where the 2 pieces meet, the hard cover is raised slightly on one side. it's very minor but the kind of thing that drives me nutty. i'm not sure if this is a problem with all of them or just mine. IF you don't mind extremely minor imperfections and you won't mind the added bulk, the dualpro is better than the slim armor imo.
spigen ultra fit: i had an incipio feather on my gs3. i got bored of the colors so i decided to try the spigen ultra fit in mint. great minimal case. feels good and adds very little bulk. once the "ohhh new shiny toy" phase runs out and i'm a bit less cautious with my g3, i'll probably end up switching to the ultra fit. the ONLY thing that bothers me about the case is the cutout for the korean antenna. if this is not likely to bother you and you're looking for a minimal case, the spigen ultra fit is great. if you like any of the incipio feather colors, i'd probably just get that since it doesn't seem to have the antenna cutout and the quality of the cases are very similar, both great.
caseology drop protection: easily the cheapest case out of the bunch it fits great. doesn't add too much bulk and it's not loose on the sides after it's on the phone. it looks great. there are a bunch of nice looking colors. it feels not so good. it's a flexible rubber material which is important because the amazon page kinda makes them look like a hard shell case. it's a very glossy feel. it's a strange slippery but grippy feel at the same time. but i tend to have clammy hands so it just starts to feel a lil gross. i really wanted to like this case so i could order a couple more in different colors but i can't. it's a shame really.
