Hello, I have both birds and have used them both on solar farm inspections without any problems. The difference is the M30T has a wider IR view and the M4T has a higher GSD. I used the same flight pattern and settings for both birds and the results were pretty close however you will finish the job a little quicker with the M30T. I never had a bad deliverable with the M30T but you just can't use Drone Deploy with it which makes some people steer away from it.
