I've used Neutol plus quite a bit with no problems regarding maximum blacks or developing time compared to Dektol or anything else. All neutral/cold tone paper developers are about the same regarding final print characteristics when used with developer-incorporated papers (which is almost all VC papers) I've never been able to tell the difference between Neutol, Dektol or the A-130 formula when examining my prints. The paper itself makes much more of a difference.
