Is there any negatives to upgrade my current project to 2018.1b

I am currently developing a project in 2017.3 and, other than bugs, I don’t really see a downside to just continuing my work on the beta version of 2018…

Is there any huge downside to what I see as ‘Upgrading Early’?

It’s not a good idea i think.

If you already have a Project on course, is better continue with the same version, and upgrade if you want before start the next one.
