First of all I don't know about or have never used fEARFUL,fEARLESS, Glasstone, Schroeder so don't ask for a comparison...I don't have one. Maybe some one else does. It is a tiny little box that looks pretty tame. I plugged it in at home and it really does get loud at least for a living room but we all know a gig is a different scenario. Bobby Scott had a gig at Cotton Eyed Joe's which is a big honky tonk and we play loud. (3 guitars,bass drums). Our stage volume was a 7 on a scale from 1-10. I can run through the p.a. as I am the sound man but I usually try to get a good mix of p.a. to onstage cabinet. Live this cabinet gets loud and doesn't mind being pushed and actually prefers it. It had no problem holding its own volume/punch/focus wise. It handled the note on my Alien "B" string quite well with no real noticeable drop off . It is not a thin sounding cabinet by any means but it also does not have a big booming bottom. To call it anemic is also NOT a word to describe this box. It is a solid sounding loud cabinet and with a little tweaking you can get a fairly fat sound out of it. In my scenario it turned out well because of the solid sound and lack of boomy bottom. It is focused and tight and easy to control. It kept the stage sound crisp and clean. I drove it with one side of my Genz Shuttle12.0 I was able to put a little bass in the subs to make up some of the boom and the mix between to 2 was wonderful. When the gig was over the 32 pound 800 watt box went out as easy as it went in when I was fresh. The Xsonics 210CF does not have the low big bottom of the 212CF or the 215CF but it is a cabinet with a purpose. I am sure it would be a quite natural sounding upright bass amp or A/E bass guitars. While this cabinet is tiny...it is not a joke...it is real gear for real bass players.
