No-one else seems to have any opinion so I'll throw in what little I do know. I'll start by stating that I have neither the knives you list, but have recently treated myself to the 888 Solution. If steel quality and build are of any concern to you, stop worrying. My 888 is a solid as a rock and I do not expect to call on the warranty for anything. My knife has already seen a couple of trips out into the field and has proven to be all I expected. It's a pleasure to use and to to own. I didn't like the military style sheath, but soon made my own out of leather (I'd love to post a picture but cannot do so!). This is just a personal choice, and the supplied sheath would serve well if you liked it. I found the final grind of the edge to be a little obtuse for my tastes, but a spell with some DMT gear soon re-profiled it to a finer edge, and now it's just about the sharpest tool in the box (If only the same could be said for me! *LOL*)
As I'm not going to be using the knife for it's intended "tactical" usage, but as a field knife, I might not be giving you the sort of info you want, but I think you'll be paying a lot more money before you find a stronger, better quality knife than the Buck Striders.
