I've never ridden on KTS, but from everyone that has them, I've heard nothing but good reviews. SPL, if not the best, is really up there with their suspension products and customer service.
Kbees are awesome! For its price, you'd be surprised on how well valved the shocks are. Although, from what I hear, they're no longer available here in U.S. (unless you have your own personal connection). I mean, you can search around, but I tried, cuz I was trying to find a set for my homie that just picked up a project car. However, they do still sell them everyday at upgarage for about ~$750http://

Stance GR+ are awesome as well. But if I were you, I'd spend a couple hundred to get the GR+ pros that come with the helper springs... just for that added comfort. I remember their first line had issues with the pillowball bearing not rotating or something like that, but from what I heard they have fixed that problem. Also, iirc, they offer custom spring rates free of charge. and since you said this is your daily, a spring rate of 7/5 w/ helper springs will feel like butter on your asss. If you do go with Stance, just make sure you mention to the vendor the pillowball issue that stance once had to make sure you're not getting the older version (the one they should have recalled, lol).
Megans- I don't really like them. They have poor valving (or at least it isn't up to par). It may not be as bad as k-sports, but you can still feel the bounciness when hitting imperfections in the road (not to be confused with stiff, which a lot of people do). My cousin has them (megan streets). He bought them last year, and at the time, I had no input on them and there were barely any online reviews or articles on them. If you ask him, he seems to like them, and they still aren't that bad of a price, but compared to stance, kts, or kbee, you can really feel the difference in ride quality, and so can he.
