The tech is the same, its mostly the hops and verification infa thats there in meshcore vs tastic.

Ive found tastic works best in like events, camping, out on the water, etc.... because it works faster at establishing that initial push nodes. Core is VERY slow at the initial day or so of populating.

That being said its all LORA. Your not wrong, core I can get into multiple states miles and miles away. Technically tastic can too, but its a longshot with their 7 hop limit.

When I worked with software for both projects, it was interesting to see the design choices too. Core had some benefits using Tastic as the model. And Tastic had some huge code cruft inside the main python cli and documentation for years. Both are still fantastic projects.
