Murmur allows voice calls between groups of Bluetooth LE capable devices. Multiple connections between devices create a mesh network, allowing group voice calling and messages for up to 16 participants. The network allows signals to be relayed between devices, allowing the range to far exceed that of a single Bluetooth connection when used in a group. Murmur supports Bluetooth hands-free kits, making it ideal for cyclists, skiers, climbers, hikers or any group activity taking place without reliable cell-tower reception.

Verdict
The clearest difference is in-app purchases: DTR 2.0 at none against Murmur's 1. DTR 2.0 also leads on iOS requirement (11.0 vs 13.0). Murmur's advantage is update cadence (weekly vs monthly). On price, ads and device support there is nothing between them.
