The clearest difference is rating: SmartBT SPK at 5.0 against NebulaBuds's 4.4. SmartBT SPK also leads on in-app purchases (none vs 12) and iOS requirement (12.0 vs 14.0). NebulaBuds's advantage is ratings volume (15K vs 1) and update cadence (every 2 weeks vs every 2 months). On price, ads and device support there is nothing between them.
