I havent got anyone else’s money tied up in my UE5 project, no specific deadlines. If I hit a blocking issue its not a big deal to wait for a fix, and keep working on other content and areas of the project. I’m not likely to be releasing anything before Epic get done with version 1.0 of UE5 so I’m not too worried about that.
All that aside, 5 seems to be built on the fairly solid foundations of 4. UI has changed a bit and there are some incredibly promising new features under the hood, but it feels familiar. That mixed with the lack of a deadline and how visually rewarding some of these new features are, means its hard to pass up just going feet first with a project in 5.
If I was working a 6 - 12 month turnaround with other guys’ money on the line, the known quantity and stability of 4 might be a better option. For beginners, there is a lot more documentation on features in 4, and tutorial content will be more reliable and easy to follow.
With time and experience on your side though, no real reason not to have fun and play with all this new stuff. Lumen is worth the price of admission alone when you get to grips with it a bit, even with its teething problems.
I imagine most here are of a similar viewpoint on it.
