Gdown,
I think you are wrong

I would go with the Ruger. The jump isn't very bad, and the quality is consistently good.
But first, let me thank you for the input and welcome you to the forum, Gdown. I am just rattling your cage. I agree with your conclusion.

A 50% price jump IS bad. ($500 + $250)
{Where I think you are right}
I would definitely go for a Ruger over a Taurus. And a used Ruger is likely to be right at the price point of a new Taurus, and just as strong as the day it left the factory.
Here's my reasoning (based on comparisons to Smith & Wesson revolvers, but Taurus' lockwork is similar, I believe).
I prefer Rugers. Here's why:
I owned two S&W revolvers in my past. Model 28 6" Highway Patrolman .357 Magnum and a K-22 Masterpiece 6" 22 rimfire. When I took the sideplate off the .22, I saw all those small parts inside (comparing it to my Dan Wesson, the only other revolver I owned at the time, which had about half the number parts as the Smith). I put the parts that sprang out back in, lubed the inside lightly and never opened it up again. I traded them off shortly thereafter. The Dan Wesson, in addition to having fewer parts, seemed to have more robust parts as well. Ruger parts are even more robust than the Smith or the DW. I like that.
On the strength question, Ruger's frames are one-piece frames without sideplates, the design was always inherently stronger (opinion alert). And Ruger doesn't just make Ruger guns. They make frames for other gunmakers and investment cast parts for many other industries. Bill Ruger was a pioneer in investment casting post-war and Ruger still is a player in the industry.
Anyhow, a little extra weight has its own advantage in a heavy-recoiling gun.

Springs. All the Ruger Revolvers use coil springs (Blackhawks, SP, S-Six models, SP and GP as well as both Redhawk models) but the Standard Redhawk's lockwork is unlike any other revolver ever made by Ruger or by anyone else. The Standard Redhawk uses a single spring to power the hammer AND the trigger return. This makes it a little harder to tune than a gun with separate springs, but if you like a unique gun, it is one.
I don't know what the Taurus has (leaf or coil) in it's large caliber revolvers, but I trust the Rugers.
By the way, the Ruger Redhawk 44 may not have the extra strength of the Super Redhawk, but it is no slouch and is probably more available (and many consider it better-looking) than the SRH. The extra metal in the frame of the SRH is overkill for the 44 Magnum cartridge. Redhawks have been around since 1980 or so and many guns are available in good condition on the used market as well as still being produced.
The SRH does have the same grip post and lockwork design as the GP100, so theoretically, grip shape is more flexible and tuning might be easier, but not so much as to make a material difference, I think.
Taurus is a fine gun and I have four (2 9mm, 1 45 Auto and 1 22 rimfire revolver nearlyl 20 years old). But my heart belongs to Ruger.
Good luck.
