if you’re on a single platform (windows) and just a few nodes, any of them should work fine.
Where it really starts making a difference is working on a lot more nodes and on multiple platforms.
From what I understand and have seen, Deadline is the biggest, heaviest of the bunch in terms of how many resources, cpu cycles, and network traffic it uses to run and manage all its database and statistics stuff.
We’re using Smedge here on windows workstations and linux render farm. Not that it means I’m endorsing it, because it can be finicky at times. It’s lightweight and fast with far fewer features, though we’ve ever really needed any databases or stats. The things we’ve wanted have actually made more sense to script linux to do in conjunction with our FTP rather than relying on the render manager to do it by putting more strain on the network and taking away from rendering CPU cycles.
Smedge is almost half the price as Deadline not to mention MUCH cheaper to upgrade (less than 27%) which becomes important when you start adding more nodes down the road.
