I had an '11 Soul and a '14 Soul. I'll start out by saying I loved the original design & am a huge fan. The original design with the metallic avocado green was awesome! When that lease was up, I got a '14. Didn't like the aesthetics as much, but it had improvements in other areas (blind spots, ride quality, etc.). It was also the best car I've ever driven in the snow thanks to a combination of TC & ESC (iirc ESC was mandated on all cars '14 & newer, absolutely wonderful technology for snow driving!). Ended up trading it in for a Forester because my wife hated stick, and also the Soul was underpowered with a 6-speed MT & ~130HP motor. Side note on the '15 Forester: I call it the best car ever built. Goes up hills effortlessly, lots of nice safety features, adaptive cruise option, amazing visibility, but...pretty bland. I almost got a second one, but the Renegade caught my eye & I dug the design, especially the interior. It's not as strong on hills, but makes up for it in a lot of other ways.
So having had two Souls...the Renegade is essentially a Soul with AWD. It's basically exactly the same car, but with a way better ride (the Soul has a pretty stiff suspension). Since I've gotten to the point where I drive more miles than makes sense to lease, I wanted to buy something fun that would also get me through the New England snow...
technically the Forester was the best answer, but the Jeep is WAY more fun, so I opted for the combination of fun & practical. I almost bought another Soul (great-looking dark metallic blue with tan leather interior, ~$24k), but for $1.5k more, I got the Jeep with AWD/4WD & vastly improved ride experience. I feel better knowing that I'll have that for the winter & also so I can have some fun going on trails with my Jeep buddies. It's just nothing something I'll have to worry about in winter. Again, the '14 Soul was the best car I've ever driven in the snow, but I can do even more with the Jeep, and again with the ride, it's just soooo much better. More solid even than the Forester imo.
I think the Soul looks better than the Renegade, especially the older models. A lot of people don't realize what great cars the Souls are & what a good value they are...when I looked, it was like the third-cheapest car on the market (after the Mitsubishi 1.2L deathtrap & Nissan Versa) but had a ton of features available in a really great car package - sit upright, lots of room, surprisingly great quality...basically a modern Saturn. The Renegade has some weird design features, like the slightly oval-on-the-horizontal side windows & stuff (fortunately it looks better in person than in pictures), but is lovable in its own way. I went with the Commando green because heck, gotta get an ugly color to match an ugly car

I actually like the kind of WWII nostalgic green it imparts to the design. Definitely getting some Jurassic Park stickers for the side doors next Halloween, haha!
Anyway - the Soul is a great car. Very underrated imo. However, if you're planning on buying a decked-out Kia model, for a little more you can get a Jeep 4x4 with a ride that is so much better it doesn't even compare.
