Yes definitely worth trying out. I’d actually bought a VAX licence just recently as I prefer that to Jetbrain’s subscription model. But with their latest 2 Resharper C++ updates, 2016.2 and 2016.3, they’ve actually made improvements explicitly mentioning Unreal Engine 4, and it did improve things dramatically so I’ve ended up subscribing… I still don’t like the subscription model, but I have to admit it’s a good product 
Anyway, main thing I wanted to mention, make sure you check this note if you’re using VS2017, I missed it initally and nearly gave up
