Springburn is the nicest Parkrun course I've done. Victoria Park is flatter but usually quite crowded, and lapping people can be tricky in places. I have the same PB for both courses, but definitely enjoyed Springburn more.
Looks like I picked the right one then, I enjoyed the variety knowing I wasn't going for a time. My usual one is Crammond which although is a lot faster it's out and back usually with wind in face while trying to hit splits so nowhere near as nice!
