I use Neutol WA almost exclusively as a paper developer, and am pleased with its slow reacting performance, one reason being that I often will develop pinhole camera exposed paper negatives in Neutol, and the slow development aids in controlling contrast.

I also like premixed liquid paper developers, and the keeping properties of Neutol are, in my opinion, on par with Rodinal. Buy a big bottle and it'll last a long while.
