Verdict
The clearest difference is in-app purchases: multiSign at none against Instasign's 4. multiSign also leads on ads (none vs shown) and device support (4 vs 2). Instasign's advantage is update cadence (every 5 weeks vs every 5 months). On price and iOS requirement there is nothing between them.
