Hey Nobel,
Yeah Biotrack and MJ Freeway are pretty common in the industry, at least they have been over the years. I've only used a few but I can try to answer your questions about them. All frustrating in their own ways.
As for MRST, have you ever tried using their platform? It's the absolute worst. I mean, it makes me miss myspace and foursquare (which I just googled and still somehow still exist). But yeah I can't believe people still give those assclowns money. MRST was my first cannabis stock, and I'm glad I only bought a handful.
To be fair. I do think they all have some issues, basing that also on what I've heard in the industry. The one I hear the most positive about is one called Flowhub, I haven't personally seen it though and the only places I've heard of using it are all in CO, so it may be a local thing.
