Give index shifting another chance. Try this: Remove the chain. Clean chain and cogset. With the chain removed, and viewing it from the rear, align the upper pulley of the derailleur on the biggest and smallest cogs. Make sure the alignment on the biggest cog is spot on. The alignment on the smallest cog can be a "hair or so" outward to the dropout. Viewing it from the rear and with the chain removed is, in my experience, the only way to align the pulley with the cogset properly. If there is nothing wrong with the dropout, derailleur and cabling, it should shift flawlessly after the initial fine tuning of alignment of the pulley with the smalles cog.
