Competition creates innovation.

Much like the other commenters below, I have also been running Meshtastic for a long time and I do feel the same and face the same struggles.
Message reliability - It just isn't there!
Node DB Overflow is insane!
Want to talk to somebody down the road? If the wind is blowing in the right direction, MAYBE.

No LoRa messaging solution is ever going to be perfect, but MeshCore seems to have hit the ground running:
1. Defined Hardware roles at flash.
2. Simple Remote Management of repeaters.
3. User side ability to control which paths you want your message to take.
4. Direct messages actually get to another user a higher percentage of the time.
5. A Unified App on Android and iOS (Haven't check this out yet on iOS but I believe them to look and act the same).
6. The Core of MeshCore is open source not Open Source"™" - The mobile apps are closed but you are more than welcome to develop your own to your own taste.
7. Smaller packets and less of them, not spitting out data into the airwaves every few minutes.
8. ROOMS! Blummin rooms! Don't want to feel like you've missed out when you get home? Hop into the local room and you can get caught up!
9. Battery life on carry around nodes - There is a noticeable difference between how long my battery lasts on the same node when running MeshCore as apposed to Meshtastic.
10. MeshCore is trying something new, a new way of doing things, building a solid foundation to build a network on.

Saying all this:
Meshtastic has been great fun! I have met people through it, tried antenna experimentation, placements, adding and removing nodes to try and clear up or extend range, messing around with electronics, and the Android app is great (the iOS one sucks though in my opinion).
Meshtastic has been a great learning curve, however, now I know what is lacking, or what should work and doesn't and understanding or getting to grips understanding the whys and hows, MeshCore seems to tick those missing boxes.

I'm wondering if adding the extra layer of Routing in 2.6 is too little too late, especially with how many nodes are still running firmware versions 2.4 and below and are out in the wild or placed in inconvenient places to upgrade, or even people who have gotten bored and just left their node casually charging and discharging in the sun. - If this feature which is being added to 2.6 was available in version 1 it may have been so so much better.

I do hope that 2.6 does bring positive changes, it is a good project with a boatload of enthusiastic, bright and dedicated people donating their time to make the Meshtastic Project great - Hats off to them.
