First off you are asking a very subjective question and we have no idea what your subject is or what qualities you like in your prints.
Second relying on Internet examples to judge technical merit is, IMO, nearly useless.
I'd suggest that Delta 3200 can do 12500 nicely given you can use times tested and published by Ilford.
For TX you are way outside the published norms. I'm not saying you can't make TX do this backflip, just that Ilford and Kodak are good at their jobs and know the limits of their films pretty well and D3200 is a faster film.
The only way you will know if TX will work is to try it for yourself.
