If you look at the first saddle, you will see that there is no curve from the deepest part of the seat to the hand hold. Compare this to the curve in the TexTan. This offers the rider crotch support. As saddle seats get longer much of this curve is lost. It may not seem like a big deal but does make a real difference especially after riding four or five hours. The only saddle I'd consider is the TexTan but would likely look for higher quality if you plan on doing a lot of roping.
I guess it depends on the Tex tan. I tried a Tex Tan imperial reiner and HATED it. Couldn't take it back fast enough. Stiff and uncomfortable, untwisted stirrups, which I hated......Perhaps an older one would be a different story. I was NOT impressed.
Perhaps for the $$ you would be better served to look for a good used one on eBay-like a used Leddy. They are fabulous.
In the past I have found some McCall wades used for about that much.
Look on Ranch World Ads and some of the FB trading pages, Barter Town, CowPuncher Swap Shop, Buckaroo Trading..sometimes they have decent stuff on there.
You could pick up a real decent used saddle for that price.
