That’s actually a great path of progression IMHO. Quite realistic as well.
The G3000 in the TBM is quite nice once you learn it. Not terribly complicated to learn overall. The G3000 in the HJet uses different touch controllers, so it’s a bit of learning required to find stuff, but overall you’ll see things are pretty similar. Once you learn to use the G3000 in the HondaJet, it’s a small step up to the Longitude and G5000. There are more steps involved and the systems are deeper, but if you already know how to use the GTC570 touch controllers, the learning curve isn’t as steep.
The C510 is nice too from what I’ve seen. I don’t own it, but those that fly it seem to really like it. My current personal choices for jets are still the Vision Jet and HJet though. They check off all the boxes for me atm.
The CJ4 is nice too. Don’t get me wrong. I just tend to prefer the Garmin glass over Collins PL21. It looks better, gives me better situational awareness (at least with how my brain seems to work), and it just a far more familiar layout since I’m so used to the other Garmin systems.
In any case, I don’t think you can go wrong with any of those jets. It really just depends upon the missions types you like to fly.
