I can't say too much against the Taurus 22 revolver i looked at the 357 tracker and after trying it out i bought a Ruger gp 100 ,hands down it's a better gun.
I dont own any Taurus handguns, so i dont think that you would have some of the problems that the larger cal Taurus revolvers have, but i do own several Rugers and imo they make a great value.
Buy the Ruger.
