I've been using Vegas since version 6, so I this is based on what I've observed over time. Most of the issues below are since Magix has taken over.

Let's begin with the upside. As for development of the program, I have been very pleased with were Vegas has come from and looks like it is going. That being said:

Upgrade policies. The idea that you can only install upgrades to your current version of Magix software and then have to pay to continue upgrading the current version because of an imposed free upgrade time limit is absolutely ludicrous. I don't have a single other professional program I use that does this.

Next, what happened to the great tutorials that used to go in depth on features and the program? What's available now is a joke in comparison to when Sony owned it. This came up because my wife is starting a youtube channel and needs to learn editing. Had to shake my head at the drop in quality for tutorials compared to when Sony had the program.

As for upgrades to new versions. First, I tried the subscription service and that was a joke. It installed wrong versions of programs when upgrading. When I followed tech supports advice on correcting things, it then caused problems with the 3rd party plugins that took more time and emails to resolve. After 2 years I was sick of the issues, cancelled the subscription, and bought 18 at the point where I could get 19 for free.

Enjoyed all the features. BUT, the fact AMD support had been pulled was a major issue for me. Now that it's coming back, it's buggy as can be. It seems Magix is blaming the AMD drivers yet . . . other editors are not having these issues with the same driver Vegas is struggling with. I checked their forums.

With all of the above, I'm now taking a serious look at switching to Resolve. Huge change in workflow, but the deficiencies with Magix I've listed here are not present. They have great in depth tutorials, some were commercial lessons that have been made available for free. Updating current versions are no problem, I was shocked that if you buy the studio version, upgrades to new versions have, so far, never been charged for. Part of the reason for this is because Black Magic makes money off their hardware and includes Resolve for free. It could change in the future. I don't begrudge Magix charging for upgrades to new versions, as you have to pay for the development.

Possible downsides to Resolve? Compared to POST, Resolve doesn't include an image editor, nor does it include a streaming program. I consider these minor issues as I have image editors and their Fusion effects program includes features POST doesn't have. Plus OBS studio is much more powerful than Vegas streaming and is free. Also, I already am familiar with it, so Vegas streaming is a non factor to me. Many other people are in this situation too. How about including a way to make Vegas work seamlessly with OBS instead of reinventing the wheel?

So Magix, If you want to keep your current customers, you need to address the upgrade issue for current versions. You also need to improve your hardware support and software tutorials. You need a set of IN DEPTH tutorials that are available for free to get new people started, or for people upgrading from Edit to POST.

Resolve is making in roads because of the free version, even into the Final Cut and Premiere Pro user base. In my opinion, for basic editing and transitions Vegas is much easier to use. Although Vegas has some upsides to it, you need to address these other issues to continue to grow.
