From the Loj you can count on 7 miles of mud.
If you want steep and less people blocking your way, go in from Elk Lake. Marcy is the most overused of all the High Peaks, with miserable trail conditions being the rule.
For a really beautiful, quiet trail with comparable elevation gain, climb Rocky Peak Ridge via the East Trail (from Rt 9 at New Russia, just north of "Malfunction Junction" on Rt 73).
