Striders are certainly well-built knives, and they have a very loyal following. My main complaint on them is that many of them perform poorly with lighter tasks that a folder in my pocket will see. Strider also has some CPM-3V folders, which I think is neat in concept but a terrible steel in practice for a folding knife that will almost surely never see usage that will test the strength and impact resistance anywhere near where 3V really shows its value and justification over a steel with higher wear resistance and lower toughness. If I want to perform Strider-tough tasks, I generally use my $55 RAT5. I've found the fit and finish is very good.
Hinderer offers the Spanto blade, which is reasonably good at lighter tasks and tough as hell. They also offer the Slicer grind which is an excellent slicer and still very strong. They also also offer a wharnnie, which is a helluva good cutter. I am also a very big fan of how they are heat treating CPM-S35VN. On the downside, they are still knives with a large carry profile, the flipper was not built as the primary action if it is a flipper you seek, and the secondary market prices are outrageous given the MSRP for these knives is actually under $400. I have found the fit and finish is excellent.
If the primary goal is a super strong knife that can take whatever, many of the ZT Hinderers rate right up there as well, and for a lot less than most.
I like the Seb 25 a lot too. It is a very practical EDC given the size and strength. It has one of the most usable grinds on the market. However, I dislike how soft Reeve hardens S35VN...especially considering that S35VN is a VERY tough steel even at 60 HRC!!! I've not found a production folder other than the ZT0777 (and a few other low-production ZT and Kershaw runs) I think that the fit and finish is comparable to.
I ultimately traded my Hinderer and bought a Tighe given the money Hinderers costs are in that ballpark. The XM is nice but it's not a Tighe Stick by any means (and this is a reason I struggle to buy BM Gold Class knives). Lionsteel and Guardian Tactical are also making some frame locks of hella strong strength, fantastic steels with fantastic heat treatments, fantastic geometry, and fantastic fit and finish.
But............if you can find it, I think the knives you will personally like most will be either a L.G. Project VECP or a Calavara El Patron, likely with a custom anodized finish on the titanium (anyone good with anodizing can replicate Stider or ZT finishes, likely for under $50).......both of these knives are absolute monsters and I don't personally think any production folder can compare to their all-around performance/build quality
