Both of those knives look terribly bulky and impractical. SXB is a no-go right out the gate.
Ka Bar fighting/ utility knife (USMC KABAR) would be in the same vein at half the price and much more practical.
Give the ESEE line of knives a look as well. Those are much closer to what I'm thinking you like about the TOPS.
Micarta handle scales, kydex sheath, super tough 1095... the difference is they will cut and carry better than that Steel Eagle.
Very similar price point and the designers/ owners of ESEE professionally teach demanding survival classes as well.
I don't question the build quality and toughness of TOPS, but most of their designs seem like they have a lot of
unnecessary right angles, spikes, and other aesthetic elements that really don't do much for the performance.
To me they're poorly designed and executed well...??
Just my personal thoughts, I don't think you'd be wrong to buy a TOPS, they're still good knives, I just don't like their shapes.
