I don't know anything about TexTan so can't give you a good comparison, but my main saddle for the last 10 years has been an Abetta. I ADORE this saddle! Have used it off-and-on, but during the summers it has gotten a LOT of consistent riding time and this is the first summer that I've noticed it starting to show its age a bit. A small scratch on the pommel and the seat is starting to look a bit worn. After a decade, it is still an extremely solid saddle. I've taken it on up to 5-hr trail rides and the comfort is hard to beat. Since it's not leather I've really beat the crud out of it too... LOTS of mountain trails, swimming, gaming, etc. It's super easy to clean and it's LIGHT! Mine is just under 15 pounds. Good for those of us with a taste for the taller horses.
As with any saddle, you have to clean/store it well if you want it to last, but I'd buy another Abetta in a heartbeat.
