More complication
The most important thing is to find out why the 485 was denied. If denied on fraud/similar ineligibility ground, there is some argument that your status may be invalid retroactively. That can be a big bear of a problem.
If the grounds are merely formal, such as missed RFE, the 485 can be reinstated or refiled depending upon other factors.
You can get back on H-1 ONLY if there is no substantive problem such as fraud, 3-10 bar etc.
This is not a simple answer. There cannot be one.
